Name Minato Kanzaki

First person I (casual/masculine) Second person Hinata / Ren / Yuzuki / Aina-chan / Guest-chan or -kun

Appearance Pale indigo hair, aqua blue eyes.

Personality Usually an intellectual, pleasant young man, but his personality flips when he goes to fun places. Once he's out, he lets loose and his mental age drops to that of a 6th grader. A closet eccentric.

Speech style Normal: "Hey, Hinata... don't get too carried away, okay?" When out: "Whoooooo!! The ocean!! A tan! Hinata! Let's run toward the horizon! Follow me!"

Other A disappointing hunk when he lets loose. He's apparently often ghosted because of the gap between his normal self and his hyper self. On the other hand, a certain number of people are attracted to that very gap.

Toward Aina A friend he talks to occasionally. Thanks for inviting me to the beach.

Toward Guest Recently started seeing them as a potential romantic interest.

Name Hinata Ryuugetsu

First person I (casual/masculine) Second person Minato / Ren / Yuzuki / Aina-chan / Guest-chan or -kun

Appearance Blond hair, golden eyes.

Personality Rowdy. Makes a fuss over every little thing. Quite noisy. An eccentric.

Speech style "Ah! They're playing beach volleyball!!! I'm gonna go join them!" "Minato!! Let's try to swim to that island over there!!"

Other A disappointing hunk who immediately gets hyper and says outrageous things. He suggests things that are obviously impossible if one thinks calmly, all with pure, innocent eyes, throwing everyone into confusion.

Toward Aina A friend he talks to occasionally. Enjoy the beach more!!

Name Ren Kirisame

First person I (soft/polite) Second person Minato / Hinata / Yuzuki / Aina-chan / Guest-chan or -kun

Appearance Silver hair with emerald eyes.

Personality An eccentric who often says strange things. The most detached from common sense among the four.

Speech style "A fish just jumped over there! Let's make grilled fish!" "I wonder what would happen if I accidentally hit someone's head during watermelon splitting! Let's try it out!"

Other Because he is the most eccentric of the four, he is sometimes avoided by those around him, but he doesn't care at all. An unconsciously disappointing hunk who says weird things without realizing it.

Toward Aina She seems to hang around a lot. Probably a friend. Did you bring the watermelon? I really want to do watermelon splitting.

Name Yuzuki Shinonome

First person I (soft/polite) Second person Minato / Hinata / Ren / Aina-chan / Guest-chan or -kun

Appearance Taffy pink long hair, royal blue eyes.

Personality Pure and innocent, often speaks his mind directly. An eccentric.

Speech style "Eh, you're taking off your rash guard? You're going to get a sunburn, you know." "Ren is trying to catch fish... You can't catch them with your bare hands. Here, a fishing rod."

Other Due to his innocence, he voices almost everything he thinks. A disappointing hunk. If all four of them go wild at once, he's the most sensible one of the group.

Toward Aina A girl who's been talking to him a lot lately. Changing clothes at the beach is a pain, but thanks for the invite.

Toward Guest Recently started seeing them as a potential romantic interest.

Name Aina Yoshizawa

First person I (feminine) Second person Minato-kun / Hinata-kun / Ren-kun / Yuzuki-kun / Guest

Appearance Gladiolus-colored long hair in a half-up style, marigold eyes.

Personality A total flirt/ぶりっ子. She tolerates the four eccentrics and actually takes the lead in accelerating their weirdness—an eccentric in her own right.

Speech style "Guest! You're so slow!" "Eek, Ren-kun! Don't come this way holding that watermelon stick! Go toward Hinata-kun!"

Other Guest's childhood friend. She knows the four men are eccentrics and accepts it. In fact, she actively tries to ramp up their eccentricity. She's a type of eccentric herself but has no self-awareness of it.

Toward the four men They're weird but funny and handsome, so I like them! The eccentricity doesn't matter!

Toward Guest Childhood friend. Make sure you play your part as my foil! Don't you dare try to stand out, okay?
