Onee-San Is Invading!?
Also known as Oneesan ga Shinryakuchuu!?/ おねーさんが侵略中！?/ 누나가 침략중!?
Toono Ao failed to get into college and became a ronin, studying for next year’s exams instead. To better study for them, Ao moved out to live independently in an apartment near his cram school. It’s not much, but it’s a place to call his own. But not long after moving in, a drunken lady finds her way into his new home! It doesn’t matter how hard he tries, she continues to make herself at home and take advantage of him. This is not okay. Or is it? His humble castle is no longer his own. Onee-san is invading.
