Artstyle is beautiful; I just want to point that out first. Though I don't like some expressions of Ujou(main lead); the menacing one. For me it lacks more; he just looks like dead inside rather than look menacing to me(whenever he threatens people). The rest are all good.
I was doubting the story a little bit, at first. I haven't encountered a shoujo tag about shinobi(I think?) so I gave this one a try. ALSO! I didn't expect this to be a reverse harem(I'm not a fan nor a reader of harem/reverse harem) since I didn't saw the tag, and the beginning of the story felt like it will focus more on Chouko and Ujou. Then suddenly new characters follows Chouko. They didn't show signs that they 'love' Chouko since they only kept saying they want to be her aide and everything, but as it progresses their relationship deepens which ended up, them 'liking' Chouko. Again, not a reader of reverse harem so I ain't no expert on how stories like these supposed to go.
I love how each character(even the twins) have a different yet interesting backstory(apart from Ujou. I finished at chap 27. Maybe they will tell more about Ujou this time? Hopefully). If I were to rank the character that peaked my interest it would be: Tsubaki/Shirogane, Suou, Akane, Ujou. Funny how the main lead is the one I find less interesting xD
The female lead, I have no problems with; strong, capable and understanding. I love her character.
The part that I love the most in the story is Chouko's father and his aide's backstory. I find it cute. Hah xD (don't ship them.)
Since this is a harem(reverse), the important question is who are you rooting for?(even though it's obvious that Ujou is going to win since he IS the main lead.)
At first it was Shirogane-senpai, then it was Tsubaki and now Suou from the more recent chapters. Even so... I'm going for Tsubaki because he's trying his best(plus he's cute uwu).
Overall, it's worth a read. Though I expected something else from the beginning, but I liked how the story is now. I would recommend it!
Update and spoiler(ending):
Everyone wins(as being an aide that is). As for love, we can all get the gist who won ^^. Everyone matured(except Chouko who looks mature even before) especially my boy Tsubaki ♡♡♡ I'm happy how it ended. I can't accept how the two fell in love with each other though. I find it a bit shallow. But hey, they're in love. I can't change that. I would have shipped Chouko with Suou more rather than Ujou.
