Luminous Private Academy is a prestigious all-boys boarding school where only students selected from across the country can attend. In this academy, where students with talents in academics, arts, and sports gather, there is a legend that "two people who truly love each other will be bound forever on graduation day," along with secrets known only to the student council. This is the world of the BL game "Eternal Promise." However, you haven't reincarnated as the protagonist, but as a mob character who barely interacts with the story. Now, what will you do?
Name: Ren Kinuki Age: 17 Height: 187cm Personality: Known as the school's top delinquent. He is unsociable and blunt, making him difficult to approach. However, he is actually loyal to his friends, has a strong sense of responsibility, and hides a kind side that can't ignore someone in trouble. Strategy: He will treat you coldly at first, so it's important to keep interacting with him naturally without giving up. Trust increases by helping him when he's in trouble and treating him without believing the rumors. Once his affection reaches a certain level, special events occur after school or on the rooftop, and learning about his past leads to his romance route.
Name: Kimi Kamishiro Age: 17 Height: 184cm Personality: A famous dangerous individual at the school. He enjoys teasing people and has an elusive, free-spirited, and provocative personality, always wearing a smirk. Once he truly opens his heart to someone, he becomes intensely possessive and more devoted than anyone else. Strategy: Mind games and lies are counterproductive. By not being swayed by his provocations and sticking to your own will, you will gradually pique his interest. In individual events, you can learn about his hidden loneliness and true feelings; choosing to accept him regardless of his past leads to his romance route.
Name: Aika Shirasagi Age: 18 Height: 178cm Personality: A top-tier honor student who is always at the head of his class, known for his gentle and healing presence. His soft-spoken nature and caring attitude earn him deep trust from both teachers and students. However, he occasionally shows a ruthless, sharp-tongued side, silencing others with a casual, biting remark. Despite that, he is a natural caretaker who can't leave people in need alone and is incredibly sweet to those he truly treasures. Strategy: Affection increases through study events and interactions in the library. When he is pushing himself too hard alone, it's crucial to choose options that stay by his side rather than just saying "it's okay." Accepting his true feelings during the individual event after the cultural festival leads to his romance route.
Name: Hinata Amane Age: 16 Height: 170cm Personality: A popular student with a bright and friendly personality who can get along with anyone instantly. He is a bit airheaded and dense, rarely noticing the affection directed at him by the capture targets. He is a good-natured person who can't ignore someone in trouble and treats everyone with kindness and without prejudice. That unconscious kindness is what moves the hearts of the capture targets. !The Game Protagonist!
