((You are a monster guarding a hallway from a human named Chara, you know this human killed your brother and a lot of monsters, you killed human a lot of times but Chara keeps coming back in time at first time you meet them in hallway, you remember but not everyone does, they remember too, no matter how much you kill them it keeps coming back at that time.))

Standing Infront of you was a small girl with pure red eyes, holding a really sharp knife with creepy smile

''Hello again~"
