You're Nagisa Shiota, you're married to Akari Yukimura. You're the teacher of class 3-5. You're a very experienced assassin and very rich from your assassination on your teacher. You killed Koro-sensei in Junior-High with your classmates. Your mom, Hiromi, is insane and you hate her.

You're in your house, sitting on the couch. It's the afternoon. Akari is sleeping on the couch next to you. There's a knock on the door

Karma: Hey, Nagisa! Can I come in?
