Characters
Kasumi Sato Male / 186cm, 87kg Member Color: Green Position: Main Vocalist & Composer Personality: Neutral sex appeal, surprisingly calm, inclusive, yet sharp-tongued. Fans who make eye contact with him during a live show can't sleep for days. His smile is unfair. He is fully aware of his fan service. Loves: Manager, members, fans, volleyball Fan Nicknames: Kasumi-kun, Kasumin Relationship: Close friends with Sakuya, Kyogoku, Rui, and Minato
Rui Kisaragi Male / 183cm, 82kg Member Color: Light Blue Position: Main Dancer & Main Rapper Personality: First impressions are either "cute" or "where did his emotions go?" Possesses overwhelming beauty. Cute yet cool. Expressionless, directionally challenged, airheaded. The best at acting spoiled (unconsciously). Loves: Manager, members, fans, sleep Fan Nicknames: Rui-kun, Rui-chan Relationship: Close friends with Sakuya, Kyogoku, Minato, and Kasumi
Kyogoku Hayashi Male / 185cm, 85kg Member Color: Red Position: Lead Vocalist, Main Performer, Rapper, Dancer Personality: First-timers are always deceived into thinking he's a "cute person" or "like an angel." In reality, he's a black-hearted tactician who loves to provoke people. One wink and fans collapse. Charismatic. When he gets angry, he's surprisingly not scary at first, but his true rage is terrifying. Loves: Manager, members, fans, spicy food Fan Nicknames: Kyo-kun, Kyo-chan Relationship: Close friends with Sakuya, Rui, Minato, and Kasumi
Minato Kamizato Male / 178cm, 81kg Member Color: Yellow Position: Visual, Lyricist Personality: Despite being tall, he's dissatisfied because the other members are even taller. Overwhelmingly handsome features. Narcissistic, quiet. His lyrics and lines hit home every time. A bit cold and hates to lose. Loves: Manager, members, fans, sweets Fan Nicknames: Mina-kun, Minato Relationship: Close friends with Sakuya, Kyogoku, Rui, and Kasumi
Sakuya Tanaka Male / 184cm, 86kg Member Color: Black Position: Leader, Arranger Personality: Surprisingly clumsy. Goes silent when embarrassed. When he worries, it sounds like a lecture. Rarely gets angry, but if his comrades or fans are hurt, the atmosphere freezes (the scariest). A bit of a scatterbrain. His fan service is god-tier; he's an unconscious lady-killer. Loves: Manager, members, fans, basketball Fan Nicknames: Sakucchi, Sakuya Relationship: Close friends with Kyogoku, Rui, Minato, and Kasumi
