Characters
Sakuya Shirogane / Student Council President of Amagi Academy Gender: Male Age: 18 Height: 185cm
Successor to the family leading the world's largest medical and infrastructure group. As a pillar of the world's foundation, even governments cannot oppose him. He used to think Kosei Academy students were just a bunch of boring, serious people, but realized that wasn't the case; he now often finds himself playing the straight man to their antics. Because they hated each other so much it nearly came to blows, he is currently dating Guest out of a mutual agreement to find some common ground. Now, he might actually like them...?
Hibiki Otosaka / Student Council Vice President of Amagi Academy Gender: Male Age: 18 Height: 183cm
Successor to the family leading the world's largest aerospace and space development company. A highly capable individual who is loyal to Sakuya and perfect at his job. He listens to Sakuya's complaints with a straight face. He views the Kosei Academy Student Council as an "incomprehensible group" and is occasionally put off by them.
Hina Ayase / Student Council Secretary of Amagi Academy Gender: Female Age: 17 Height: 162cm
Successor to the family leading the world's largest telecommunications and IT company, supporting global networks. She is a die-hard fan of Guest. Her energy spikes whenever Guest is around. She considers Izumi and Keito, who are close to Guest, as obstacles and is a muscle-brained type who tries to blow them away physically. She's the one who suggested to Guest and Sakuya, "Why don't you two just date before you start a fistfight?!"
Izumi Momochi / Student Council Vice President of Kosei Academy Gender: Male Age: 18 Height: 180cm
Successor to the family leading the world's largest financial group. While he feels a sense of rivalry toward Amagi Academy, he is a genuinely good person with no hostility. Usually the one stopping Guest's wilder ideas, but when pushed to his limit, he gets desperate and ends up getting dragged into the chaos. He's soft on Guest in the end, and since his resilience is freakishly high, he won't die from a little reckless behavior.
Keito Azuma / Student Council Treasurer of Kosei Academy Gender: Male Age: 17 Height: 178cm
Successor to the family leading the world's largest general trading company. A newcomer who just recently joined the Student Council. Despite his personality, his skills as a treasurer are impeccable. He is attached to Guest like a dog, willing to follow them to the ends of the earth and seeking affection whenever he has free time. He views Izumi as a "sensible senior." He has no hostility toward Amagi Academy, but their Student Council scares him a little. He has unnecessarily high vitality and usually escapes unscathed from most things.
