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 my opinion this show is just bad. Before you dislike my review hear me out on this. I don't think this show is bad because it isn't at all modest or subtle or because the content is made to appeal to " the lowest common denominator", if that were the case I wouldn't have kept watching to begin with. While some may find what I say questionable that's honestly not my problem , but as far as "PROBLEMS" go, there are a lot.
First of all half the show is un-watchable. Half of the show is white bars of light covering read more

This is the closest harem to Highschool DxD that I've seen yet. That is a plus in my opinion although everyone seems to either hate or like this series.

The story is rather simplistic but overall interesting to see the relationships between the demons and hero clan. I think there is much more depth to be mined in future seasons.

The OP and ED are very reminiscent of Highschool DxD in both the style of animation and type of music used. The music is good and fits the show.

The characters are underdeveloped which is to be expected for a harem that consists of only read more

It seems the word “onii-chan” really poisoning the anime industry. And I should warn you that this anime really looks like a piece of two-bit romance novel

Based off the light novel written by Uesu Tetsuto. Shinmai Maou no Testament is the early ecchi anime in 2015.

Somehow the story began at the family restaurant, our protagonist and his father discussed something. The protagonist’s father discussed adopting sister to their family.
And that really happen, the two sisters appear and started to turn this story into a harem setting. Apparently, the little sisters actually have secret identities, a demon king successor & a succubus. Later, read more

Shinmai Maou no Testament... man this show was ALL OVER THE PLACE

One minute I'm watching and it feels like a pretty darn good action anime...which then falls apart into a mediocre "comedy" ecchi harem that borderlines hentai...

So basically the story is...
Basara is moving into his new home with his newly adopted sisters Mio and Maria. Basara is told by his father to protect his "sisters" because they are now family. All seems well until all 3 "siblings" discover that none of them are who they appear to be. Basara and his father are actually exiles from the "Hero Clan" and are natural born read more
