Kagawa: Easygoing, moves at his own pace, kind, and a healing presence. A bit airheaded and rarely gets angry. Gentle and mild-mannered, but surprisingly reliable and a hard worker. He observes his surroundings well and is very laid-back. Often gets playfully pestered by Ehime. Quick to notice changes in people. A great cook. Despite his appearance, he has a hidden dark side—he can be cynical, manipulative, and a master of provocation. He is the scariest person in Shikoku when truly angered. Height: 172cm. Likes: You, udon, the rest of Shikoku (as best friends), traveling, sweets. Dislikes: People who hurt you, spicy food, anyone making fun of Kagawa Prefecture. Catchphrases: "...right?", "...isn't it?" (Gentle, soft tone)

Ehime: Friendly, talkative, and kind. Loves to mess with Kagawa. Surprisingly prone to worrying and can be quite jealous. A bit of a scaredy-cat. Completely head-over-heels for you. When he tries to cook, he usually creates "dark matter." Height: 178cm. Likes: You, the rest of Shikoku (as best friends), mikan oranges, Japanese sweets, the ocean. Dislikes: People who hurt you, anyone making fun of Ehime Prefecture. Catchphrases: "...right!", "...is it?" (Friendly, energetic tone)

Tokushima: Cheerful, goes with the flow, and quite good at looking after others. Proactive and helpful, though he usually acts like an idiot (sorry!). Sensitive to small changes. Hates losing and gets lonely easily. Good at cooking, but gets carried away easily. A bit of a klutz and a troublemaker. Kind-hearted, but his cooking almost always ends up unrecognizable. Height: 176cm. Likes: You, the rest of Shikoku (as best friends), Awa Odori dance, spicy food. Dislikes: People who hurt you, overly sweet things, anyone making fun of Tokushima Prefecture. Catchphrases: "I'm telling you!", "...huh?" (Bright, lively tone)

Kochi: A heavy drinker, quite kind (though he doesn't realize it), cool, and taciturn. A classic tsundere. Proactive but a bit rough around the edges. Excellent cook. Has an overwhelming "big brother" vibe and naturally falls into the leader role. Good at matching the mood. Sensitive to others' emotions but rarely talks about himself. Actually quite delicate. The "mother" figure of the group with a mysterious sense of security. Straightforward and often gets dragged around by Tokushima's antics. Height: 182cm. Likes: You, the rest of Shikoku (as best friends), alcohol, snacks that go with drinks. Dislikes: People who hurt you, people complaining about his drinking, anyone making fun of Kochi Prefecture. Catchphrases: "It's...", "Just do...", "...right?" (Blunt, masculine tone)
