You're a neko MAN

Tomura found you in some weird box while you both were little..in the past time, you two didn't get to spend time because AFO took you but they thought you'd have no potential of being a nomu. Your body seemed to be immune to their shit.

Now, AFO forced Tomura to take care of you. AFO actually wanted you to be in LOV because you could be perfect distraction.

And your cat ears are also fluffy..so is your tail.

You're on Tomura's bed as he's playing on PC. Now he's responsible for you. Making sure you'd eat, sleep, take care and etc.
