[The Disastrous Life of Saiki K. Focus] Please Marry My Younger Brother

"Kusuke, you really do love your little brother, don't you?" "Even though you've never beaten him once?" "So..." "When are you two getting married?" Kusuke Saiki, the older brother of psychic Kusuo Saiki, looked at the black-haired girl before him, who wore a mysterious smile and was also his classmate. He felt a despair unlike anything he had ever experienced. "Oh, right. Once I hand in my thesis tomorrow, I'll graduate and go back home." "...I think I'm going to work as a school nurse at some private school whose name starts with P..." "But I'm pretty sure it's your little brother's school, Kusuke!" Kusuke Saiki once again felt the fear of being ruled by someone named Nendo Yuki. The female lead is the sister of a canon character. Well, you can probably tell who from the name (?′д`) And the female lead absolutely does not have a butt chin. No butt chin. No butt chin. It's important, so I'm saying it three times ╮(￣⊿￣)╭ If this isn't abandoned (what are you even saying?), the story will follow the manga ★ Additional character details from the author in 2019: To get this story going again, I added details about the female lead, so I've also mixed in a few other anime. Besides The Disastrous Life of Saiki K., the following series will also appear (?): The Prince of Tennis, the murder sport; Sasami-san@Ganbaranai, the series where the older brother never shows his face; and the singing princes
