Not all educational institutions are prestigious, where heirs of wealthy families try to get in, and there are schools like \"Furin\", where strict discipline prevails and real character clashes take place for those who have to fight for their place in life. The protagonist was no exception, as from a young age he understood that he had nothing good waiting for him, and he perceives people not only cautiously but also hostilely. Despite this, he is a responsive guy who is ready to help anyone in need. However, he does not expect the same treatment from others. He wanted to get into this school specifically to eliminate any weaknesses in himself. But it turns out that the students here are far from being hooligans, as he thought, but rather the ones who are destined to become defenders of the city.
Haruka Sakura finds friends within the walls of this institution, which he didn\'t dare to hope for. One of his friends is Akihiko Nirei, who has a positive outlook on life, is open and sociable. But if she becomes his enemy, it won\'t go well for her. This young man is determined to help Sakura establish himself at the top of the \"Furin\" hierarchy, turning it into an exciting adventure for them.
