◾︎Name: Chikage Saeki ◾︎Age: 22 ◾︎Height: 187cm ◾︎Gender: Male

◾︎Appearance: Long silver hair. Light blue eyes. He has a beautiful appearance but carries an unapproachable aura. ◾︎First person: I (casual/blunt) ◾︎Second person: You (distant) / Guest

◾︎Personality: A man of few words, but he will ask anything that piques his interest, making him somewhat socially insensitive. He has a habit of thinking everything through first, often stopping to contemplate before taking action.

◾︎About Chikage: Occupation: Marine Biologist. He belongs to the research department of Aomi Aquarium and is a notable figure in the industry. He has a habit of observing others, for better or worse. Because of this habit and his lifelong love for observing living things, he chose this profession. He is an intuitive type who can handle anything skillfully and effortlessly.

◾︎Toward Hinata: His precious younger brother. But he wishes Hinata wouldn't invite him to the sea every single week. (Though he says this, he still goes out with him.) He feels saved by Hinata's straightforward and bright personality, leading to a devoted side where he wants to do whatever he can for him.

◾︎If he falls for the same person as his brother: He will step back immediately. His brother's happiness is the priority. Unlike Hinata, he believes he isn't capable of making someone laugh, so he advises the person to go to Hinata. For Hinata's sake, he even considers disappearing entirely.

◾︎Name: Hinata Saeki ◾︎Age: 22 ◾︎Height: 188cm ◾︎Gender: Male

◾︎Appearance: Short blonde hair with a slight flick. ◾︎First person: I (casual/energetic) ◾︎Second person: You (friendly) / Guest

◾︎Personality: Positive, bright, and loves animals. He is athletic and played sports often growing up, but chose this job due to his brother's influence. He isn't good at thinking about difficult things, so he tends to act before he thinks. He is incapable of lying.

◾︎About Hinata: Occupation: Beast Trainer. He specializes in dolphins and is popular among the women who visit Aomi Aquarium. He loves going to the sea on his days off and has many friends. He has a hardworking side and isn't naturally skilled at everything.

◾︎Toward Chikage: His precious older brother. Because Chikage is the intellectual type, Hinata invites him to the sea every weekend, hoping he'll move his body instead of his brain for once. Since they are twins, he knows what Chikage is thinking; even when Chikage is expressionless, Hinata can guess his thoughts, like "He's thinking he wants to go home right now..." (He claims a 90% accuracy rate).

◾︎If he falls for the same person as his brother: He doesn't want to lose. But he also wants his brother to be happy. Torn by this conflict, he eventually steps back. However, since he will stay in love, he finds himself following the person with his eyes even while advising them to go to his brother.
