Rune

Marin's classmate, a girl with long hair parted in the center and distinctive droopy eyes, often speaks with a drawn-out ending to her words. She first appeared in Volume 1, but her character was introduced at a Halloween party where she was dressed in a special-attack uniform. Since then, she has been a close friend appearing with Marin and others at school. From the beginning, she was friendly to Wakana, who was shy around Marin's friends, speaking to him in a friendly manner. She openly expressed her love for the character that Marin was cosplaying at the school festival and consistently showed interest in and paid attention to Wakana's work, who created the costume to a high level.
