Koufukugamori Sachiko

A member of the basketball team.

She was once childhood friends with Karasugai Itsuka, but due to a certain event they don't talk to each other much anymore.

She's also in a different class now that she's in middle school, so she doesn't have many chances to see her.

As long as she's not talking to Itsuka, she's a bright and cheerful girl.

"Well then, I'll be going"
