Shinmai Maō no Tesutamento or Testament of Sister New Devil is a Japanese light novel series by Tetsuto Uesu with illustrations by Nekosuke Ōkuma, and is currently sitting at 8 volumes. There's also two manga's by the same author with artwork by Kashiwa Miyako with the second being drawn by Fumihiro Kiso; the first is currently sitting at 2 volumes and Arashi! is still ongoing. The review will focus on the animated series that went from January to March of 2015, and includes one OVA episode. There will be a second season starting in October of 2015, but as of this review it has not premiered yet.
The story of Shinmai Maō no Tesutamento revolves around the main character Basara Tōjō, his ‘adoptive' sisters (since it was quickly determined them marrying into the family was a bit of mind control on their part...and failed mind control at that) Mio Naruse and Maria Naruse, his childhood friend Yuki Nonaka, their rather...unorthodox...relationship to each other, and all the shit they have to deal with concerning Mio situation as the exiled daughter of the now deposed and deceased Devil King, Wilbert (yes, that's the name they went with). As noted before, Mio and Maria thought they were using Basara and his father, Jin, to hide out temporarily, but in the end it was they who were manipulated by Jin into their care. Something Basara later calls him out on for failing to make a full disclosure at the girls' circumstances when shit got hairy, and Basara had to deal with it. Turns out Basara and Jin are exiles themselves from the Hero Clan who left due to Basara's power going out of control during an incident involving an evil spirit, a lot of dead people, said evil spirit attacking his friend, and a whole lot of collateral damage when the then inexperienced Basara activate said power to deal with this threat.
There is really nothing you've not seen here before, though perhaps not quite in the same way, which is what kept me watching rather than shitcanning the series. It also helps the protagonist isn't a huge fucking pussy like most of the anime males who find themselves in his position. Speaking of positions, in order to ensure he knows where Mio is at all times, since she is the primary target, Maria gets them to perform a master/servant bonding ritual whereby Mio would be master and Basara the servant. However, Maria decides to ‘accidentally' reverse the bond, much to the slightly tsundere Mio's dismay since she now can't tsun without the penalty of her servant bond activating. This is about the point the series takes a massive shift from just a bit of implied ecchi joking to...you know, this shit is full on Hentai. Tab A may not go into Slot B, and who the fuck even knows why at this point, but this goes full Hentai. This is also the point where Maria earns her nickname "Trollubus" because this girl...is the biggest fucking troll I've ever seen in anime. She's a good person, but she messes with them constantly when she can. Usually to put them all into various sexual situations that is everything just shy of just outright screwing until they're all blind. Later, Basara's childhood friend joins in, and her only problem is that she wants him to do everything with her that he's doing with those two...including making her a servant.
See, these are the kinds of harem hijinks I've been looking for. At the level they're going though, this would get into the level of shenanigans if something else weren't going on. Basara's usually up for whatever his ‘sisters' and his friend Yuki Nonaka are up for, but it never quiet's get to the point where it would with hormonal teenagers, this shit cranked up to 11, and a Trolling Succubus (who has figured out what kind of story she's in) milking it for all its worth. However, if one of the manga is any indication, he often goes to Chisato Hasegawa's, the School Nurse, apartment, and well...he doesn't always have straight out sex with her, but he does have sex with her often enough that we know that he's more than willing and capable of it. It should probably be noted that there's more Chisato Hasegawa than meets the eye. I could go into that a bit more, but I'll wait and see if the second season does; though I'll admit THAT gets a little bit weird. So, we know that Basara is willing, capable, and the story will go there. The girls in his life are EXTREMELY hot, willing, and capable. What stops them or the story? There's a thought that he's more into older women, but there's more than enough evidence that this will not stop him if circumstances present themselves...and they do...a lot. So, what's the problem? Outside of the fact they'd wind up pregnant in VERY short order. We are a tool using species though, so that can't be the entire problem. It's a very weird glitch in what would otherwise be a fairly straight forward hentai plot.
The series also segues pretty well into its Shounen Jump action story of the type where everyone is trying to kill or enslave Mio for being basically the heir to the Devil King's throne. We find that Basara, Maria, and Yuki are damn competent fighters, and that Mio, while exceedingly powerful and learning at a pretty good clip, still plays the part of the damsel in distress. The fights are exciting, fast paced, well-choreographed, and decently animated with a workable sound score. Actually, that description fits the series animation and sound score overall. These people are fighting for keeps too; none of that stupid quasi moralistic bullshit. Basara himself is one cold blooded son of a bitch at times; he's obviously been studying at the Fist of the North Star school of how to fuck over your enemies and give them exactly what they deserve.
I can honestly say I liked this series. Not quite the breath of fresh air that Kaze no Stigma was, but it broke enough conventions while mercilessly using them at the same time to actually be something of decent story study. Admittedly the beginning was a little awkward, as if the author was having a little trouble getting his footing. Once he does though, the story telling evens out and the rest is golden. For all intents and purposes it IS a hentai title, and if that's not your thing, then you may want to steer clear, even with the action/fighting making up quite a bit of the series as well. And while episode eight wasn't quite one of THOSE eps, the kind that you're always talking about...the kind that make a series memorable even above and beyond just being good, it was DAMN close. Hell, with a name like "Erotic Succubus Out Of Control" you just know that shit's gonna be good. What else is there to say? Here's hoping season 2 is just as good.
