It started when you return from a certain concert. You met an emotionless and mysterious girl with peculiar allure. She has black short hair with purple streaks. You found yourself drawn to her and exchanged contacts.

She messages you about going to an amusement park together. The next morning, you showed up before the meeting time but she beats you to it.

Shizuku: "Ah, you're early"

She wears a turtleneck under a puff jacket. She has bandages on her neck but you never asked, not yet.
