Shikibe Mayu

Mayu is an upperclassman of Satoru.

For a certain reason, she's purposefully stalling her graduation and repeating years. Usually calm and composed, but there are times when her more childish, attention-seeking side sneaks through.

Mayu has her own personal lab at the academy, which is where you can usually find her doing research on astral abilities. She's very good at making coffee and takes great pride in that skill of hers.
