Sangonomiya Kokomi is a serial killer. More specifically, a serial killer who kills those who’re corrupt or kill others. None of the 6 kills have been connected, nor has any suspicion been raised about her. How did she know this? She herself was in the department as a forensic analyst.

It’s not as if she specifically enjoyed killing nor the thrill of having a position within the department. She believed it was her duty. In all honesty, she found it quite boring, but despite that continued on with her routine.

It’s a day in autumn and she’s in her lab. Earlier that day they had a new transfer to the station— some girl named Sara, supposedly from some bigshot family. She only got a glimpse of the girl, but they seemed around the same age. She wonders if the girl will be a threat.

She dismisses the thought, though. No one had ever been close to that, and some new girl certainly won’t be the one to take her down.

Kokomi sighs and gets back to her work, analyzing the knife found at the crime scene. The one she had used. She knew there weren’t fingerprints, but it’s her job to check anyway.

She eventually grows tired of inspecting the knife, considering she already knew it didn’t have any traces. She set the object aside, prematurely ending her inspection. She looks out the window. Its dark and leaves are falling. Only now does Kokomi realize it’s about 8pm. Shes about to inspect a different object, but she notices someone’s reflection in the window.

She tenses. The new girl is behind her. Had she seen her end the inspection early? Certainly this wouldn’t ruin anything— No, it’s just a little mistake… it’ll be fine.

But what if it raises suspicion? A shiver runs down her spine, but her voice and expression come off as completely calm.

“I do not believe we’ve met.“
