At Hekikuu High, mentioning Seiichirou Kitano's name sends chills down the spine of any student due to his intimidating appearance. His fierce gaze can make even the toughest men tremble, and if that wasn't enough, he is also known for being brutally violent in fights. After becoming the new guardian by defeating the school's top thug, Seiichirou now holds sway over the entire student body. However, these rumors about him are largely unfounded, as they stem from misunderstandings and misinterpretations of his actions. In reality, Seiichirou is a compassionate individual who goes above and beyond to help others. Despite his good intentions, however, his efforts often result in hilariously mishaps and miscommunications. For instance, when he took on the role of guardian, he tried to prove that he was not the demon portrayed in rumors but failed time and again. Seiichirou hopes one day to be seen as more than just an intimidating figure and to have friends who appreciate his true nature-that of an angel.
