The Testament of Sister New Devil Manga / 漫画 新妹魔王の契約者 #1
The Testament of Sister New Devil Vol. 1
Combining action and comedy with the supernatural genre, The Testament of Sister New Devil is a high octane romp about a high school boy and his two succubi step-sisters.
ALL HELL BREAKS LOOSE!
Basara Toujou is hesitant about his father’s sudden decision to remarry, and yet can’t deny it comes with a couple perks–two adorable little sisters. But Basara’s new family isn’t all it appears to be, and when his father leaves on an abrupt business trip, Basara learns that one of his new little sisters, Mio, is actually heir aparent to the Demon Lord, while the other sister, Maria, is Mio’s succubus attendant.
Realizing that his sisters are running for their lives from demons, Basara offers to help in any way he can, but ends up getting more than he bargained for in a magical pact with Mio. Surviving demonic attacks is one thing, but can the pair endure the pact’s unique, lustful “side effects”…?

No respect for myself for enjoying this as much as i did but CANNOT RESIST

I enjoyed this quite a bit more than I expected.
Such an interesting start to this tale. Well big sister certainly has the boing happening. That succubus though, what a brat. Well, I suspect things are going to get a lot more interesting (and dangerous) starting next volume. Art, very nice. The girls are all gorgeous. The backgrounds are decent. Dialogue, well, given the subject matter, I found it to be more palatable than I expected. As a Southern Baptist, I worried this series might be super anti-Christian (like Gabriel Dropout), but it just focuses on the demons & the protagonists. So, I don't feel bothered in any way, like I did with the aforementioned Gabriel Dropout. Characters, interesting, intriguing, entertaining, & some of the girls, totally adorable.

More of a 3.5 star rating;
Usually I can’t read ecchi stories since I typically end up really disliking them, but I think that I’m starting to like this one.

This was the best manga series I read in 2018. Highly recommended.

Love it
I rated this well because it has my favorite kind of story. Male protagonist, step sister love, Loli, funny moments, and great illustrations. Looking forward to volume 2. Great manga while deployed. If this was a show I would watch it over and over.

A decent story, so far, but too sexy for my taste.

Ein ziemlich guter Manga zum Anime: The Testament of Sisters new Devil
August 24, 2016
This series doesn't try at all to be unique. There's just so many cliches that could of easily been avoided. The Mc has a strong urge to always protect woman, a jealous childhood best friend, angry red haired tsundere and loads of fan service, even for the underage girl. It's nowhere near as bad as some other titles based off light novels but it's not all that good either I feel this could of been a well done series but the author is just an uninspired perverted fool that has somehow got an amazing artist to draw out his poorly done story. With that said, it's still a fun guilty pleasure to sneer at from time to time.

Not as fun as it could have been. This manga is for fans of action and hentai, I guess. The problems is that there was very little action and the sexy parts were also limited. So... throw in more of one or both.

I love this. That's all I can really say.
