Everyone Is Miserable? Say No to Yandere Girls!

After transmigrating to Tokyo, Imai Jona, a born esper, decides to start an agency to change the state of the girls' bands, which can only churn out the same old stuff, and introduce the world to girls' bands that truly shine. "Imai Lisa? The kindest sister in the world, even though we have different parents. I love her most!" "Roselia? My big sister's band. I love them!" "Mugen-dai MewType? Arale's band. Love them!" "MyGO!!!!!? Ave Mujica? Doesn't that go against the kind of world I want?" "Wait, why are there more and more bands? And what is Millsage?"

In this world, where there are many more girls than boys, Jona doesn't even have time to refuse. Why are all the girls in front of him looking at him so strangely? "What do you mean Tsumugi Sakiko opened a paradise for every girls' band in my honor?!" How terrifying! Absolutely horrifying! I have to find a few genuinely reliable, nice girls to stop Sakiko's plan. Nagasaki Soyo, Misumi Uika, Viola. They all look like they should be nice girls, right? "There are more nice girls? ...Holy crap, is Todo Fujiko even human?!"

In the end, the introverted, socially anxious Jona comes to a conclusion: I absolutely will not marry a repressed, obsessive woman!
