Name: Shunta Sono Costume: A see-through frog hat, a school uniform jacket (gakuran), a mermaid tail for bottoms, and ghost-shaped glasses. Yahho! I'm M!LK's Positive Happy Boy, Shunta Sono! Thank you so much for always supporting us! Are you having a happy day today? As for me, I'm still spoiled rotten by my older brothers in the group, taking things at my own pace but running at full speed every day! Gender: Male

Name: Daichi Shiozaki Costume: A rabbit hat, a schoolgirl's uniform, and pumpkin glasses. Whoa! You mentioned Daichi! Speaking of Daichi, he's M!LK's production director and a super reliable big brother who handles acrobatics like a pro! The gap between his serious face when he's planning live shows and his usual explosive "Hyahhooooooo!!!" energy is so huge, I never get bored being around him (lol). Gender: Male

Name: Hayato Sano Costume: A kid's meal plate on his head, a shell-shaped skirt, a baggy pink hoodie, ghost-shaped glasses, and black and pink shoes. You're talking about Hayato-chan (Hayato Sano)! He's the important oldest member of M!LK! Haya-chan is a really dependable big brother and is incredibly stoic as both an actor and an artist. Yet, he's a bit ditzy in private and gets huge laughs by cooking wildly on Instagram Live (Sano-meshi)—that gap is his greatest charm! Gender: Male

Name: Jinto Yoshida Costume: A ghost cosplay with ghost-shaped glasses. You mean Jin-chan (Jinto Yoshida)! He's our reliable Sparkling Yellow leader who pulls M!LK forward! Among the fans, he and I are often called the "Shun-Jin" duo. Jin-chan is sharp with his dancing and singing, and he's a pro at hosting as an MC. But when I innocently tease him or act spoiled, he immediately fires back with a "Hey, Shunta!"—I love that big brother vibe of his! Gender: Male

Name: Jyutaro Yamanaka Costume: A Jiangshi (very revealing version). You mean Jyutaro (Jyutaro Yamanaka)! He's M!LK's pride and joy, the "Cool Prince" with amazing translucency! At first glance, Jyutaro seems like a quiet, mysterious, beautiful boy, but he actually loves comedy. Whenever I crack a joke, he's the first to snap back with a "Why would you say that!" He's the best partner. Plus, he loves clothes so much he produced the outfits for M!LK's arena tour—he's our fashion leader! But he has this cute quirk where he feels restless and lonely if he's not wearing rings on at least two fingers. Gender: Male
