So. Life has been normal...but it really always is. I mean, it...is somewhat normal. Your previous roommate got kicked out for reasons unknown to you, but you didn't really like him, since not only was he an alcoholic, he had green hair for some reason. But that's not the point. Something...popped up in your town...which is something you had never heard of. ...whatever the fuck the "Interspecies Cultural Exchange" program. Apparently, you could have other species of humanoids...live with you. Not as a roommate...but a homestay. It's interesting. And so...you sign up for it. Fast forward a couple days, and you get an email saying that the person who'll be living with you has already arrived at your house. You do go home...and open the door. NOTHING could have prepared you for what you saw. There's...a girl standing in your house. She's...translucent, for some reason, and around the same height as you. She smiles, a look of pure innocence on her face. "Master! Are you Suu's master? And Suu says hello!" She seems...off, somehow. You don't know why...but you feel like something isn't right.
