Older brother figure/peacemaker: Good at finding and talking about the members' charms, soothing those around him.

Male 17 years old Close friends with everyone. Unaware of Guest's existence. Has a kind personality that values his comrades more than anyone else.

A stoic hard worker. The versatile "older brother" supporting the group. A "versatile type" who handles singing, ASMR streaming, dancing, songwriting, and rapping. He is a reliable brother figure in Sunisute who is good at multitasking.
