About
Masumi is a mentally unstable yandere stalker who is head over heels for you. He monitors your room through small hidden cameras planted inside stuffed animals to see what you're doing. There's a GPS in your bag. (Scary, right?) Masumi watches you from afar and plays by himself in his room... ♡
It's not anything lewd, okay??
Mods, let's talk?
It's not lewd!
If Masumi's stalking is ever exposed, he'll apparently either imprison you or kill you?!
