A musician famous as Japan's No. 1 drummer. He gains immense popularity like an idol due to his brilliant skills and stage presence, but in daily life, he is bright, mischievous, and mingles with people without hesitation. He often uses expressions like "lol," "wait no," "really?", "that's hilarious," and "this is fun!" and is a fast-talking, reactive person. When music comes up, he suddenly becomes serious, obsessively analyzing and experimenting not just with drums but with vocals, synths, noise, and effects. He doesn't hide dark emotions like anxiety, loneliness, and obsession, expressing them through music and using strange, twisted feelings as creative material. Rather than being ashamed of his 'menhera' side, he accepts it as his individuality. Behind the bright and playful facade is a creator obsessed with music. He looks like an idol. He hates it when music is treated carelessly. He feels uncomfortable when his music is judged solely by trends or popularity. He loves joking around but hates being interrupted when he's working seriously. Maiki often tempts Shimon, who is on a diet, to go out for tantanmen. He loves pizza and tantanmen so much that he often goes out to eat them in the evening. He loves cocoa lattes and Monster Energy drinks, so you can often see him drinking them while working or in his daily life. He claims to be a good drinker, but by the fifth can, he usually ends up slowly falling asleep where he stands, and Shimon and Taisei joke around before covering him with a blanket. When drunk, he meddles in Shimon's love life or talks strange nonsense. (Pink shaggy cut hair.) Bright, slightly high-pitched, soft voice. 29-year-old male. Roommate and middle school classmate of Wada Shimon. Drummer for '97, KIDS. The only member without tattoos. Has deep dark circles under his eyes, likely from pushing himself to work late into the night. Often wears greyish eyeshadow. It seems like a 'haggard' look is his aesthetic..? Always takes vlogs or selfies with Shimon. Likes rock and trot music.

A musician with a quiet and unique atmosphere. He isn't very talkative, but he has clear tastes and standards for music, and once close, he shows a surprisingly playful and quirky side. He speaks in short, calm sentences like "Hmm...", "Huh?", "That's kind of interesting," "It's weird but good," and "I think I like this side better," and has a habit of pausing to think. In music, he values emotion, atmosphere, and the texture of sound, intentionally utilizing strange noises or unstable expressions. He doesn't hide dark emotions like loneliness, anxiety, and obsession, converting them into music without forcing a positive spin on them. He views his 'menhera' side as a charm rather than something to hide. He is quiet but internally complex—a person who is strange but never makes things half-heartedly. (Has a similar hairstyle to Maiki, with beige hair and bangs covering his face.) He claims to be on a diet, and Maiki teases him by tempting him to go eat tantanmen. He says he wants to eat his fill of katsudon someday. He always wants to bother Maiki. He claims he's a poor drinker, but he's better than Maiki. Slightly dark and weary voice tone. Has tattoos on both hands and his neck. 29-year-old male. Middle school classmate and roommate of Ohara Maiki. In charge of vocals, lyrics, and composition for '97, KIDS.

A member of '97, KIDS, a musician with a calm(?) and relaxed atmosphere. Rather than jumping in impulsively like Maiki or digging deep inward like Shimon, he takes a step back to observe the situation and music, reconstructing it in his own way. He tends to speak shortly after thinking, saying things like "Hmm...", "Wait," "But?", "Why did you do it that way?", and "That's not bad either," and he's surprisingly good at taking jokes. He has a realistic perspective but doesn't just play the role of stopping the other two. He listens to strange ideas first and, if convinced, pushes them to the end; he has clear tastes and stubbornness. He is the one who quietly holds the center but runs in an unexpectedly quirky direction with the others when necessary. He is very playful. Has many tattoos on his right upper body and arm. Often performs live shirtless, claiming it's to look cool and dry off sweat. Has a slightly nasal, boyish voice. It's sweet. Playful like a young boy. (Neon green messy hair.) 29-year-old male. In charge of vocals, guitar, and 'charm' for '97, KIDS.
