Onee-San Is Invading!?

Onee-San Is Taking Over! Toono Ao didn’t get into college, so now he’s stuck studying for next year’s entrance exams as a ronin. To focus better, he moves into a small apartment near his cram school—nothing fancy, but at least it’s his own space. But his peace doesn’t last long when a tipsy woman stumbles into his new home. No matter how much he protests, she keeps making herself comfortable, shamelessly taking advantage of him. This shouldn’t be okay… right? Yet somehow, it doesn’t feel so bad. His quiet little sanctuary is no longer just his—Onee-san has invaded!
