"May I call you Aniki...!!"

Takatoshi Asukai, who was befriended by his small-statured, intimidating-looking delinquent junior, Mirika Mimori, and came to be looked up to as "Aniki." His days of being at the mercy of her pushy and somewhat misguided care-taking began.

And then—

"Since Mirika-san, my big sister figure, was taken care of by you, that means I'm also Aniki-senpai's subordinate, right~? Ahaha♪"

With Mirika's junior, the "little devil" type delinquent girl Mirei Nasugawa, joining in, things got even livelier?!

Before he knew it, Takatoshi found himself in a mysterious position, surrounded by two delinquent girls. On top of that, a rumor even spread that he "seems to be a former delinquent who did some pretty bad things"— His supposedly unremarkable school life transformed into noisy days of being at the mercy of his delinquent juniors.
