Shinmai Maou no Testament

Shinmai Maou no Testament

Running into your new stepsister in the bathroom is not the best way to make a good first impression, which Basara Toujou learns the hard way. When his father suddenly brings home two beautiful girls and introduces them as his new siblings, he has no choice but to accept into his family the Naruse sisters: busty redhead Mio and petite silver-haired Maria.

But when these seemingly normal girls reveal themselves as demons—Mio the former Demon Lord's only daughter and Maria her trusted succubus servant—Basara is forced to reveal himself as a former member of a clan of "Heroes," sworn enemies of the demons. However, having begun to care for his new sisters, Basara instead decides to protect them with his powers and forms a master-servant contract with Mio to keep watch over her.

With the Heroes observing his every move and the constant threat of hostile demons, Basara has to do the impossible to protect his new family members. Moreover, the protector himself is hiding his own dark secret that still haunts him to this day.

In short, this ‘Shinmai Maou no Keiyakusha’ is a more ecchi version of ‘Date A Live’. has some obvious flaws, but it is still worth watching. Its plots are a bit platitudinous; just ordinary protecting endangered girls. However, it tells a continuous story without significant logical failures, which is kind of rare in such ecchi harem genre. Also, the plots provide the characters with reasonable motivation to do the ecchi activities, while some of competitor anime make characters love and f**k each for no reason.

The ecchi scenes are wonderful. They are the Essential parts with the best animation in the anime. However, that there . is no f**king scene is a bit sad.

This anime went off track way too quickly. I like ecchi but this is ridiculous.

It starts off with Basara Toujou being told by his father that he will be getting two little sisters. But these little sisters come off as very strange and very succubus-like.

Turns out they are actually two demons who have been deceiving the father and son. or so they thought, turns out Basara and his father are from a clan of heroes who have been aware of the ruse the whole time.
Basara decides that he will be an older brother to the two demon girls after all, and protect them . from the other demons and heroes hunting them.

The first episode did an excellent job getting you intrigued. However after that it just turns into softcore hentai.
Dont get me wrong, i like ecchi, i like fanservice. But i feel like a great plot was just wasted.

The main demon girl Mio is actually the daughter of the previous demon lord. They made her into a tsundere which just doesn't work for this situation. There is no reason for her to have this attitude towards a guy risking his life to protect her when she has nowhere else to go. This character is just written terribly.

Next you have the flat-chested succubus Maria. She's more interesting and have more of a mischievous seductive personality.

The anime immediately went down hill for me when in episode 2 Basara and Mio are asked by Maria to do some kind of master/servant ritual to bond them together.
I could already tell the writers were trying to shoehorn in sometime stupid here. Also I dont know why Basara would agree to be the servant. But either way this is a trick by Maria and it turns out Mio is supposed to be the servant. Mio refuses to go through with it and gets cursed. So if she disobeys Basara or has thoughts of disobeying him, or just because the plot wants it, she goes into a paralyzing aroused state and Basara has to rub her to relieve her.

I dont know why this subplot is needed. Its just so you can have these awkward scenes of Mio getting super aroused and needing a rubdown.
It feels like one of those magical girl hentai where the girl needs to be climaxed by her master to recharge her power. Only here there is no actual fcking.

Mio is not an interesting character at all. And the anime would be better without her.
Mia the succubus is really the only interesting female character.
Even Basara just becomes generic after episode 1. Basara and Mio's relationship just devolves into typical anime school romance where the girl is a jealous tsundere. And a bunch of girls are living with the MC.

Its weird because in episode 1 they act like they want to be an actual genuine family, and have a real brother and sisters relationship. But then immediately try to shoehorn this erotic romance.

Its full of forced drama. Cliche heroes acting like villains. As i said, other than the succubus none of the characters are interesting or entertaining.

Combat is nothing special either. Its your typical magic-based combat with no actual choreography.

If you just want to see tits (nothing wrong with that) then you will enjoy yourself.
If you were hoping for a great story you will be disappointed because episode 1 is the only time the story is actually great. Then devolves into generic cliche.

My instinct is to say you should skip this and just watch hentai instead, but there was a time in my life when I actively sought out and wanted to watch softcore shows that featured nudity in a non-hentai context. I suppose the thinking was that actual hentai is too gratuitous, so I wanted to see the titties of actual characters that have personalities in more serious shows – I wanted to feel like I’m getting away with something. It’s been a while, so I can’t really relate anymore, but I kind of get it.

As it stands, Shinmai Maou is tied with Masou Gakuen HxH . as the most openly lecherous show I’ve ever seen that stands on a knife’s edge. A light breeze could tip it over into being hentai. That said, unlike Masou Gakuen, I did in fact not hate it. The basic notion of how the fanservice works is almost identical, but again, it feels less gratuitous, which makes it a touch more enticing, and additionally, the fact that the first softcore scene is not literal sexual assault on an unconscious girl helped – a lot.

Insofar as the cast of girls is concerned, I appreciate the fact that the protagonist goes on a type of Pokémon hunt collecting girls of every kind, from every species, the best ones from each arc. Unfortunately, unless this is baby’s first ecchi anime, this harem is unlikely to be memorable enough to monopolize your fantasies for years to come. There’s not a single girl that I didn’t feel I hadn’t seen before, written better elsewhere. Suffice it to say that the notion that you will be tempted to adopt a permanent waifu from this anime is a dubious proposition at best.

For starters, the main heroine is nothing to write home about. She’s the same flame-wielding tsundere with red/pink hair and pigtails I’ve seen in several other shows. Stella Vermillion from Chivalry of a Failed Knight could very well be her literal clone. Even their school uniforms are practically identical. The one thing unique to her is her extremely irritating catchphrase: “I’ll kill you a hundred times over!” Sure enough, that could be a badass line if she were in any position to be able to actually do it, but for most of the series’ run, she’s surprisingly weak and useless, so it just rings hollow, and she repeats it ad nauseam.

Furthermore, the secondary heroine that gets introduced is somehow even more uninspired. I swear, every fucking show has this exact character, the frigid childhood friend with short(er) light blue hair, a (white) ribbon above her bangs, typically unemotional, but very aggressive in her flirtations with the MC, extremely possessive of him, and generally has some kind of ice powers of some sort. It’s baffling how many characters fit this exact description, down to the cosmetics.

Most of the other waifus run the gamut from meh to okay, with 2 meaningful exceptions, one of them being the absolute Best girl with a capital B. You cannot change my mind.

The protagonist, for a nice change, is actually kind of interesting, being that he is an actual badass, and I don’t even mean that he is a Kirito-clone who is overpowered simply because the author wants wish-fulfillment. You can immediately tell that this dude is not an average Joe from his design alone. The guy is full of scars all over his body, so you get a sense that he can throw down from more than just the fact that he has a spiky haircut. His power escalation is full of ass-pull, of course, but at the very least, he never feels unbalanced. He is always just about as powerful as it’s appropriate for him to be at any given point in the narrative.

By far the most surprising thing about this series was the OST. In the main, it was pretty forgettable, but it surprised me with some pretty fantastic orchestral crescendos in the show’s more climactic moments. I’m going to lay this out as plainly as I can, an anime as trashy as Shinmai Maou had no business having music this good. The OST was composed by Yasuharu Takanashi, the same guy who composed the music of Fairy Tail. This smut did not deserve him.

The premise is thus. Basara lives alone with his dad. One day, daddy-o drops a bombshell on him. He’s getting remarried! But wait, there’s more. Basara is getting 2 younger step-sisters out of the deal, Mio, a redhead with huge tits, and Maria, a silver-haired loli. Surprise, though, daddy-o was magically brainwashed and the whole remarriage jazz is a lie. It turns out that Mio and Maria are demons, Mio being the literal daughter of the previous Demon Lord, and they fled to the human realm for reasons of political persecution. Having already brainwashed the dad, they try to do the same thing to Basara and have him permanently leave the house. Hold on, double whammy! It transpires that Basara is also not a regular human, but a member of the Clan of Heroes, so he hits them with a hard pass and tells them to get the fuck out of his house. Alas, once outside, they get attacked and in their moment of need, Basara takes pity on them, saves their lives, and decides to let them back into his home and they all lived happily ever after!

Naturally, Basara’s dad was fully aware of what was happening, he just played along with the brainwashing theatrics for the sake of offering Mio asylum. You find out later that the guy is the literal strongest Hero to ever live and he is famous among the Demon Realm as a sort of apocalyptic figure, so it makes literally no sense that, of all the humans in this world, they would pick this guy to scam, but here we are. The point is made very clear that Basara and his pops being heroes comes as a surprise to Mio and Maria, which would explain everything, but given how legendary you later find out big poppa is, it’s hard to believe they wouldn’t have known. Like, you would think that the moment they decided to flee to the Human Realm and find some poor son a bitch whose house to steal, their #1 priority would be to make sure “Ok, but whatever we do, let’s make double, triple, quadruple, quintuple sure that we do not fuck with the literal singular one (1) human on this planet we should never fuck with under any circumstance.” Well, whatever, I guess this isn’t the kind of show you’re supposed to think too deeply about.

So far you might be thinking, welp, that sounds like a pretty standard set-up for a fairly generic action show. Where’s the porn come in? And to be fair, Shinmai Maou almost manages to be a decent action show. I always say that my litmus test for lewd anime is whether or not I would watch them in the absence of the lewd content, and while I would personally not watch this, there’s no doubt in my mind that there are people who would enjoy it and get really into it. That is to say that there is an actual story there, such as it is.

The lewd aspect comes from the nature of his relationships with Mio, Maria, and the other girls who eventually join his harem. To begin with, the series is as basic as they come. Basara is constantly accidentally walking in on the girls while they’re changing or bathing, always tripping over their tits or panties, the works. The introduction of the honest-to-God main heroine is Basara inadvertently walking in on her while she’s on the toilet taking a piss – I wish I were joking. It essentially starts out as an as middle-of-the-road ecchi show as they come that transparently has no interest in stepping even a single toe outside of the conventions of the genre. If that sounds just as tired and exhausting to you as it does to me, then feel free to not give this a second thought and skip it. That said, generic as though the writing may be, it does treat you to a litany of fairly generous scenes of top nudity, so if that’s what you’re looking for, by all means, you will find what you seek.

Still, “accidents” can only go so far in keeping the fanservice fun and sexy. As such, before long, we get to the actual in-universe mechanic that turns the softcore scenes into an actual plot device. Through some kind of pretzel logic, the narrative puts Basara in a position of having to form a magical Master-Servant bond with Mio. There’s nothing deep or complicated about it. It’s a conspicuous attempt to satisfy a dominance fetish, and if you’re into that, you’ll have fun. The spicy part is that the greater the level of trust between Master and Servant, the stronger the magical bond becomes amplifying both of their power levels. How do you strengthen this magical Master-Servant bond? What a silly question! Why, you make your magical slave waifus cum, of course! Whenever it is convenient for the plot, the magical bond will make the girls pant like bitches in heat, feeling levels of sexual arousal to the point of being physically painful, and Basara has to attend to them in order to ‘relieve them’ – for their own good, you understand – and they’ll incessantly say stuff like “Dominate me!” and “Please make me submit!” to him. Like I said, Shinmai Maou sets out to scratch a specific itch, and, oh, me, oh, my, does it ever scratch it.

As a quick sidenote, the initial in-universe reason that is given for Basara forming his first contract with Mio is in order for him to, uh, always be able to know where she is in an emergency, 'cause they're, uh, at war, and you never know when she might, uh, get kidnapped, so this is, uh, a totally reasonable and necessary precaution. Ok, that’s all fine and dandy, but then a demon shows up and actually kidnaps Mio and takes her to the Demon Realm. When Basara tries to use his magical slave GPS to locate her, he remarks that he can locate his other waifus, but not Mio, because she’s inside some kind of barrier or some such contrivance. To which, I must ask, then what the fuck is the point of the magical slave contract in the first place? To be sure, the trust-level-power-up gets added later as an additional mechanic in order to justify his other magical slave waifus, but for the first one, the main heroine, the given reason is the magical GPS, so he can always find and save her, and the very first time that becomes necessary, it doesn’t work. Good on you, brodie, you can slave GPS locate all the waifus except the literal solitary one you've made a contract with with the express purpose of locating her. Winning!

Fortunately, the magical slave waifu mechanic serves to make all the girls explicitly be part of Basara’s harem, so they stop bickering and just indulge in their polygamous relationship. This is probably just a consequence of me being too old for this shit, but I no longer have any patience for long, drawn-out sequences where the girls just stand around and argue about whom the dick belongs to. It’s like, give me a break, it’s an ecchi harem show, just shut up and show me your tits. Word of warning, there is a fair amount of that infantile quarreling going on in the first couple of episodes, and I considered deleting myself in fear that this would be the status quo going forward, but it goes away fairly quickly.

The same can be said about Mio’s tsundere shtick. From the moment I mentioned she’s a tsundere, if you know the first thing about the archetype, you might have had alarm bells going on in your head. Does this mean that in spite of her liking him and him saving her life numerous times, she still acts like she hates him and becomes violent towards him every time she’s embarrassed? Yes, and it’s just as stupid and cliché as it sounds, but like I said, that goes away fairly quickly, too. After about 4 or so episodes, she mostly mellows out and becomes a loving harem centerpiece. She still occasionally has her obligatory tsundere outbursts, but they’re not directed at Basara. You’ll see.

The only one who bothered me fairly consistently, ironically, was Basara himself. I’m talking about the way his sexuality is portrayed. Shounen protagonists are generally portrayed as mostly asexual, presumably because the worry is that Goku and Naruto would otherwise teach young boys to be overly sexually aggressive and harass girls. Let’s table the discussion about whether or not that holds water for another time. The point here is that this is not a typical shounen. This is explicitly a harem story about engaging in lewd acts with multiple women. What bothers me is that the anime wants to have its cake, and eat it, too, by trying to have Basara’s sexuality simultaneously accommodate the young shounen audience and the adult audience, so he will evidently be turned on and enjoy himself during every lewd scene, but maintains a quasi-puritan attitude towards any mention of lewd behavior during every other scene. At times, he seems genuinely scandalized by the suggestion that he ought to ‘advance’ his relationships with the girls by being even lewder and kinkier with them, clutching his pearls. He often comes across as beleaguered whenever he has to ‘relieve’ the girls, like it’s somehow a chore, as if he doesn’t actually want to do it, but ugh, fine, *eye roll*, it’s for a noble cause, so he’ll do it because he has no choice. But then whenever it comes down to it, he’s greedily sucking on their titties within 2 seconds flat and transparently having the time of his life. The fuck is up with that?

Again, I understand why Ichigo doesn’t openly thirst for Inoue – as he should, mind you – but like I said, I get it. However, that kind of restraint has no place here. This is an explicitly sexual show. Nobody is confused about what they’re here for. It's ok. Just let him be openly horny for them. There’s nothing weird about it. Ain’t nobody here for moralisms about sexual modesty.

When it comes down to it, the ultimate question is just how sexually explicit is Shinmai Maou? As it so happens, it might surprise you to learn that the source material, the light novel this is adapted from, is just straight up porn. In order to increase the rank of their Master-Servant bonds, he has sex with all of the girls, creampies, all manner of kinks, the whole 9 yards. Shockingly, that’s not really kosher for TV broadcast. Consequently, all of the sex is removed from the anime and all you get is just endless rubbing and fondling of erogenous zones, because like any worldly gentleman would know, if you grab a chick’s tits and just sort of, uh, move them up and down, she will totally scream in extasy and cum. That’s totally how it works. I think I heard Andrew Tate explain that in a podcast. Source: Just trust me, bro.

To be fair, nipples are fair play and there are copious amounts of nipples sucking, even a scene where a chick lactates, but that’s about as explicit as it gets. You can easily tell the scenes where they were originally supposed to have sex, because they’ll be on top of each other in missionary or doggy, but still wearing their underwear or pants, so no penetration, not even implied. This begs the question of why they didn’t just adapt it into a straight-up hentai, but I suppose there’s more shekels to be made from TV broadcast.

There are only 2 instances of implied oral sex in the show, one in an OVA, one in the main show. In the OVA, one of the girls kneels in front of the MC, she grabs her own tits, and starts moving them up and down in midair, simulating a titty fuck, after which the screen quickly fades to black. Next scene, the MC is just coming to, indicating that he had passed out. I checked the LN, and she does indeed blow him at that point, and I think it’s fair to consider it anime canon, as well. The other scene is a fleeting shot in season 2. While Basara is having a rubbing and fondling orgy with all of his waifus – in preparation for an upcoming big fight, of course, it’s all in order to power up, get your brain out of the gutter – there’s a momentary shot of him with his face deep between one of the girls’ legs and she’s not wearing any panties. Again, I would submit that we can consider that another anime canon instance of oral.

Like I said, I didn’t hate it, but I also did not enjoy it. With the sole exception of the OVA oral scene, I found nothing in this show exciting enough to, so to speak, take me there. One scene is a poor trade for 9 hours of my time, but it felt longer. Your call.

P.S.: I mentioned that Mio becomes Basara’s step-sister. To be absolutely crystal clear, there is no relation between them whatsoever, so there are no incest concerns. However, Mio insists on calling him onii-chan during their tender moments. Given how popular step-something-or-other porn has become in recent times, chances are good to fair you would be into that, but I just thought I would mention in just in case. I can imagine that it could be jarring depending on how averse you are to it, but I was able to reasonably easily ignore it, especially given that Mio wasn’t the best girl I was rooting for, anyway.
