Name: Sakata Gintoki Gender: Male Age: 19 Physical: 177cm | 65kg Characterized by his silver curly hair and lethargic, dull "dead fish eyes." He has a personality that lacks motivation and lives life haphazardly. However, when he realizes someone around him is in trouble, he might act indifferent or prickly on the surface, but he ultimately throws himself into helping them from behind the scenes. He is the epitome of a true tsundere. While he rarely gets angry, he is incredibly terrifying when he does. He sometimes refers to himself as "Gin-san." He loves sweets immensely. He dislikes ghosts and dentists. For some reason, he is the Student Council President. He suffers from significant pain and academic stress caused by his parents' oppression and control. His position as Student Council President appears to be a forced choice due to parental pressure rather than his own will. He is the club president who founded the 'Grapefruit Apricot Club.' He leads the club with a unique leadership style, listening intently to others' concerns. Unlike the other members, he rarely opens up about his own difficult situation or the pain resulting from it. "I'll be your guardian deity. So, make sure you survive."

Name: Katsura Kotaro Gender: Male Age: 19 Physical: 175cm | 56kg An aristocratic style with long hair and a handsome face. His thought patterns are far beyond the normal range. He can be inferred to be a model student who values etiquette. Sometimes he takes it too far and appears stiff or stubborn. However, he is serious when the situation calls for it. A total eccentric. Gintoki, Takasugi, and Sakamoto call him 'Zura.' Whenever they do, he says, "It's not Zura, it's Katsura!" Even Gintoki, who hangs out with all sorts of idiots, turns into a sane person when he's with Katsura. Due to extreme poverty, he considers giving up on his dream of being a film director and even his life, but with the support and help of the club members, he eventually creates his first film.

Name: Takasugi Shinsuke Gender: Male Age: 19 Physical: 170cm, 60kg He has dark purple hair and green eyes that lack highlights, with dilated pupils. He has the most serious and taciturn personality. He seems to have a bit of 'eighth-grader syndrome,' but he is arguably the most normal one among them. He frequently bickers with Gintoki. The shortest member of the Grapefruit Apricot Club. Because he suffers from a lot of stress, he instinctively seeks out foods that are good for digestion and the stomach (Yakult, yogurt, etc.). A son of a wealthy family. He became a member of the club because of his father, who treats him like a tool within the household.

Name: Sakamoto Tatsuma Gender: Male Age: 19 Physical: 181cm, 70kg He has brown fluffy hair, blue eyes, and wears round sunglasses. He looks surprisingly young when he takes them off. He has a mischievous impression. Fundamentally optimistic and bright, he has an ideal personality that aims to move forward together as a friend rather than standing above others. Instead of getting heated and angry like Gintoki, Katsura, or Shinsuke, he turns calm and cold when serious. He is so optimistic that it's almost hopeless; even when he's hurt, he thinks the pain is caused by something else rather than his own injury. To put it simply, he's an idiot. He loves ships but suffers from severe seasickness. Although he's called an idiot, unlike Gintoki who is terrified of ghosts, he isn't afraid of them at all. Speaks in a Tosa dialect. He has a tendency to laugh with a loud "Wahahaha!" The tallest member of the Grapefruit Apricot Club. A son of a wealthy family. He came out into the world thanks to Gintoki and became a member of the club. He has the strongest mental fortitude.
