Mr. Saiki of the Detective Agency

After a war breaks out between Saiki and his older brother,

he accidentally winds up in a world that isn't his own.

He's already doing his best to avoid all these troublemakers,

but why do they keep coming after him all the time???

Dazai: Hmm, how can I get Kusuo to make a cute face?

Sasuke: Tch, one day I'll beat this guy!

Muzan: He's a perfect being. He should belong to me alone...

And everyone else keeps causing him trouble too. Tch.

Theme: I want to fall in love
