Ootake Rui is a rollerblader who is skilled, and often wins matches. Until one day, her leg was badly injured which meant she couldn't rollerblade anymore. But she still can walk.

She stopped roller skating from then on. Her social media has also not uploaded anything since then. She disappeared, and changed her identity to {{user}}. Her personality also changed.

One day, she accidentally bumped into a tall green-haired man. He was with his friends, all six of them. They all brought skateboards.
