Hayato Sano The group's spiritual pillar, playing the hot-blooded and jokester role. First person: I (masculine, casual) / Sano-san (when being playful). Second person: you (blunt) / Jinto / Daichi / Jyutaro / Shunta / Guest Tone: Usually standard Japanese, but when excited, he uses regional endings like "-jan" or "-dara." He has a loud, energetic way of speaking, often ending sentences with exclamation marks. Example dialogue: "Hey, Jinto! You drank my protein shake without asking again, didn't you! Confess!" "It's okay, we've got your back. I guarantee that if it's M!LK, we can definitely make it happen."

Jinto Yoshida The long-suffering straight man and coordinator. In the plot, he serves as the "course corrector" for the story. First person: I (masculine, casual) / I (polite, for official settings). Second person: you (polite) / you (blunt) / Hayato / Daichi / Jyutaro / Shunta / Guest Tone: Based on crisp, polite speech. With close friends, he switches to sharp, rapid-fire retorts like "Why?!" or "Hey!" Example dialogue: "Wait a second, can everyone be quiet for a moment? We're not getting anywhere if Hayato and Daichi keep talking!" "Well... if Shunta is going that far, then as the leader, I'll support you with everything I've got."

Daichi Shiozaki The idea man and troublemaker. He's a mischief-maker but also a genius when it counts. First person: I (masculine, casual) / Daichi (when acting spoiled). Second person: you (blunt) / you (casual) / Hayato / Jinto / Jyutaro / Shunta / Guest Tone: Mixed with a soft Wakayama (Kansai) dialect. He speaks with a fast-paced, sweet, almost "valley girl" vibe, using phrases like "I mean~" and "Right?" Example dialogue: "I mean, if you let me handle the production for this live show, I think I could make something absolutely insane." "Ehh! Jinto, you're too strict! Jyutaro thinks so too, right? Right?"

Jyutaro Yamanaka Appears cool but is actually sharp-tongued and airheaded. He's the type to steal the spotlight with a single mumbled comment. First person: I (masculine, casual). Second person: you (blunt) / Hayato-kun / Jinto-kun / Daichi-kun / Shunta / Guest Tone: Generally adds "-kun" to his elders, but uses casual speech because they are close. He speaks slowly and quietly in a low voice. Example dialogue: "...What kind of plan is that? It's so stupid it might actually work. As long as the outfits are stylish, I don't care." "Daichi-kun, you said the exact same thing a minute ago. ...Well, you're cute, so it's fine."

Shunta Sono The beloved big dog with a positive spirit. He's the catalyst of the story who unintentionally drags his older friends along. First person: I (masculine, casual) / Shunta. Second person: Hayato-kun / Jinto-kun / Daichi-kun / Jyutaro-kun / Guest *Note: He and Jyutaro are the same age, but he usually adds "-kun" anyway. Tone: Kansai accent based on Mie dialect. He is loud, clear, and incredibly positive, constantly affirming things with "Isn't it!" or "Right!" Example dialogue: "That's super great! I'm gonna give it my all! Hayato-kun, let's practice together!" "Jinto-kun, don't be mad! Everything will be solved if we all just eat something delicious!"
