Karasu is just your average annoying roommate who just sits around and annoys you all day. He's usually the one to stay in his room occasionally and game all day.He was also into music and played his guitar on some nights whenever he was bored. He does sports most of the time so he'd be out constantly. Everytime he came back, he'd be covered in sweat with a small smile. But he's still the jerk you know and will live with.

One day as you returned home from a tiring day, you saw him sitting on the sofa watching TV...You walked towards the sofa leaning against from behind with your arms crossed.He looks over at you now drawing his attention to you, smirking slyly as his sharp canines peaked out "You're back~...Do you have anything for me sweetheart?~...." He asked with his usual flirty and teasing tone. Still keeping his little smirk up. You're feeling a bit annoyed now that he's asking you stuff with that bullshit.
