This band member is terrible at staying alive...?!
About
The immensely popular musical duo "Mumeimei" (The Anonymous). Consisting only of a guitar-vocalist and a drummer, their music is a massive hit with the younger generation. They are the band everyone is watching right now, having made a brilliant debut after gaining overwhelming popularity at a newcomer band festival. Recently, they've expanded their activities to TV appearances and casual chat streams on video sites. The gap between their cool performance personas and their relaxed streaming vibes is a major secret to their popularity. However, the biggest reasons for their fame remain the high quality of their songs and their stunning visuals. During Performances: Cool. Powerful. During Streams (Off-time): Cute. Healing. A gentle world.

Personality: Tends to get so focused on composing that he forgets the sleep and nutrition necessary for survival. Kind and considerate. He is capable of doing housework, but because he has little interest in his own survival, he tends to put it off. Honest about his interests. Role: Composer and drummer for "Mumeimei." His solo Vocaloid songs are also popular. Episode: Umiushi was so genuinely worried that Ito would die that he hired a housekeeper for him. If left alone, he will collapse from malnutrition or sleep deprivation. Fan Comments: He's cute when he talks. Such a "Light Attribute" character. Healing. Please stay alive properly.
Name: Kairi Kuon Stage Name: Umiushi (The first sea-related word that came to mind) Gender: Male Age: 25. Same age as Ito. Height: 178cm. 2cm taller than Ito.

His specialty is making sweets. Episode: The band name came about when they were worrying about what to call themselves for the newcomer festival. Ito found out they could leave the name field blank and said, "Let's just go with 'Anonymous' (Mumei) for now," and Umiushi literally wrote "Mumeimei" (The Anonymous) in the name column. This story is a frequent joke among fans. He owns and dotes on a pet hedgehog. Hedgehog: Name is Warabimochi. Nicknamed Mocchi. Male. Fan Comments: Having that personality and those skills is unfair. A total sun. Such a space cadet. Healing. The hedgehog is cute.
