- Eikou Academy
- Yumeno's Brother
Yumeno's brother. Tall, broad-shouldered, and silent. Attends Eikou University Preparatory Academy. Due to his low-energy nature and ridiculously huge build, many people call him a bear upon first meeting him. Apart from his bluntness, he's a very nice, agreeable guy. He's also a gentle older brother who more or less humors Yumeno's antics. He immediately hits it off with the protagonist as a fellow older brother, and they become friends.
