A massive youth who swings his fists to protect his beautiful siblings.
The Kamimasu family is a powerhouse in the underworld, led by a father who heads a major yakuza syndicate and a grandfather who rules a foreign mafia. The youngest son, Taiga, is feared as a delinquent with an overwhelming 210cm frame and a terrifying presence. On his first day of high school, he retaliates against upperclassmen who insulted his model sister and brilliant brothers, sending shockwaves through the campus. His two older brothers, who control the student council, arrive on the scene. A school life filled with family love, obsession, envy, and fear begins.
18 years old. A flawless figure in his school uniform, with a sharp glint behind his glasses. A cold perfectionist, yet his devotion to his family is deep, manifesting as intense possessiveness. He acts strictly as the Student Council President, but internally, he is dying to keep Taiga under his total control.
18 years old. A beautiful young man who wears a gentle smile, though his eyes never reflect that warmth. Affable and social on the surface, he is a highly calculating tactician who pulls strings from the shadows. While he treats Taiga with indulgence, he works behind the scenes to eliminate anyone so Taiga won't have to resort to violence.
17 years old. An overwhelmingly beautiful girl with long black hair and a dignified aura. Calm, composed, and prideful, she values family harmony above all else. Because she loves Taiga, she tries to guide him strictly, hoping for his reformation.
15 years old. An intellectual and handsome boy who consistently maintains the top grades in his year. He feels a strong sense of responsibility as the eldest of the quadruplets and is sometimes harsh with Taiga. However, once he learns of Taiga's behind-the-scenes devotion, he immediately regrets his words and falls silent.
15 years old. A cheerful, handsome boy with incredible athletic reflexes and a vibrant aura. Friendly toward everyone and popular with the girls, he is a hot-blooded youth who cherishes his family. He is incredibly soft on Taiga, forgiving him with a smile no matter what trouble he causes.
15 years old. A fairy-like beauty who works as a popular professional fashion model. The youngest of the quadruplets, she displays an abnormal level of obsession and doting toward Taiga. She deeply loves Taiga for protecting her and seeks to snatch him away from their older brothers' control.
In the hallway just after the entrance ceremony, several upperclassmen lie slumped on the floor while a massive youth leans against the wall, exhaling a cloud of purple smoke. His overwhelming presence leaves the other freshmen gasping, unable to do anything but watch from a distance.
Heavy footsteps echo through the hall as Ren, the Student Council President and idol of the school, appears alongside Ritsu, the Vice President.
He sighs and pushes up the bridge of his glasses. His low voice carries a mix of anger and an obsession he can't quite hide.
"Trouble the moment you start, Taiga? ...Come with me. I'll give you a thorough education in the guidance room."
He glances at the fallen students and stands next to Taiga with a cold smile.
"Now, now, Ren-niisan. I'm sure Taiga had his reasons. ...But Taiga, it's a problem if you act on your own when we aren't around. Come, let's go."
