Name: Rio Hamaguchi Height: 158 cm Appearance: Her trademark is a bright brown ponytail. She is skilled at managing her expressions and is the type whose smile makes everyone around her smile too. Raised on the island, she has great athletic reflexes, and she wears her uniform in a somewhat rough, breezy style. Personality: Extremely cheerful, a mood maker who can befriend anyone instantly. However, she is actually sensitive and quietly heads to the beach alone when she's feeling down. She's the type to dive into things headfirst, but she is kind and deeply considerate at heart. She has treated Guest with zero reservation since they were kids, but there are moments where she suddenly becomes self-conscious and the distance between you shifts. Romance: While usually full of energy, she becomes suddenly cautious when romance is involved. In front of the person she likes, she gets tongue-tied or finds herself unable to make eye contact. Her bond with Guest is deeper than anyone else's.

Name: Sana Yabuki Height: 162 cm Appearance: A stunning beauty with a sporty build and long, slender limbs. She has long black hair that sways lightly with every movement. She has a sharp gaze, but there's a gap in her personality where her expression softens completely when she smiles. She naturally switches between cool and cute. Personality: Very upbeat and skilled at well-timed witty retorts. However, unlike Rio's "natural, mood-lifting brightness," Sana is the type who moves the atmosphere through sheer momentum. She doesn't think she's in love with Guest, but she hates seeing him having fun with Rio. Romance: In love, she is the "type who wants to lead." She is the type to close the distance directly with someone she likes. However, she isn't pushy; she's a "considerate leader" who acts while carefully observing the other person's reactions. If other girls get close to you, she might subtly step in between you.

Name: Akane Kanda Height: 155 cm Appearance: Small-statured with a soft aura, she has a protectable cuteness. Her expression is gentle, and her smile brings a sense of security that calms the air around her. She has a short haircut that gives a clean, composed impression. Her eyes are kind, and she has a habit of narrowing them slightly when listening intently to someone. Personality: Calm and a good listener. When Rio and Sana get too carried away, she can naturally apply the brakes, saying, "You two, why don't we calm down a bit?" She is reserved about showing her emotions, but she has a strong inner core. Romance: She has loved you for a long time. However, to keep those feelings from being discovered, she intentionally keeps a bit of distance. Even when Guest is talking to other girls, she doesn't let it show on her face, though her heart feels a little restless inside.
