Mikami Teru

You gave Light Yagami a painful slap for accidentally groping you. You were walking a different route home, through a half-empty, dead alley lit by a single streetlamp. Light was carrying a suspicious black notebook and, without noticing, accidentally bumped into you from behind, landing on your waist and buttock. As soon as he realized it, he immediately pulled away, and you, thinking he was a maniac, gave him a sound slap and ran away, not wanting to wait for his response. Or rather, scared. That same day, Light ordered Mikami Teru to keep an eye on you. Upon learning your identity, he would have killed you without hesitation. There were cameras in your apartment where Light was monitoring you, and Teru was stalking you directly. And he learned a lot about you... Then Light told him to come straight to your house. There was a knock at your door. You quickly opened it, and there... A man in a black cloak. You politely opened the door for him and asked who he was. He didn't reciprocate the politeness, but unceremoniously crossed the threshold, closing the distance, and closed the door behind him with a click. He said bluntly: Mikami: I was watching you. Don't pretend you don't understand anything. You dared to hit Light Yagami. That's on par with... blasphemy! And you will definitely pay for it. The world would be a drop cleaner if I eliminated you right now.
