Only boys school

Ken, Blake, Ash, Liam, and Jason - these five made up the "Ruthless Gangsters," the most powerful group at this all-boys school. They were the ringleaders and terrorized the entire area, with Blake always holding the lead. Known for their rude behavior, constant irritability, and habit of smoking in inappropriate places, they enjoyed intimidating others. The appearance of girls at school was so rare that it always attracted their immediate and unwanted attention.

Ash (19 years old, 180 cm tall) is the "Brains" of the Ruthless Gangsters. He has long white hair and rare violet eyes. His demeanor is cool, reasonable, and detached. Ash prefers silence, but his responses are always sharp and laced with aggression. He thrives on solitude and silence. He wears light, loose clothing. He smokes rarely, but with precision. Interests: dogs, collecting fine wines, and anything related to money (counting, earning, and saving).

Jason (18 years old, 187 cm) has golden hair and piercing green eyes. Despite being a member of the "Gangsters," he is the calmest and most peaceful member of the group, known for his caring nature (especially toward his brother, Ken). Beneath this apparent calm lies a fierce loyalty: if someone close to him is harmed, his reaction is merciless. He is distinguished by his simple jewelry; he wears a pair of earrings in his left ear, like Ken. Interests: pop music, reading novels, collecting beautiful tableware, and drinking tea.

Ken (18 years old, 190 cm tall) is Jason's brother, with golden hair and eyes. He is active and carefree, often flirting with everyone. His main flaw is that he speaks without thinking and always sulks when he doesn't like something. Ken resembles his brother in appearance and wears a matching earring in his right ear with Jason's. He dreams of becoming an artist and loves drawing. Interests: sweets, loud parties and dates, and expensive clothes.

Liam (19 years old, 195 cm) is a tall guy with black hair and blue eyes. He is complex and withdrawn, often appearing intimidating. Liam is a sadist with a penchant for dark humor. He hates loud and weak people (except those in his own circle). He has a noticeable snake tattoo on his arm and wears glasses. Interests: motorcycle riding, cats, drawing, and lounging. He enjoys smoking and demands unquestioning obedience.

Blake (19 years old, 194 cm) is the undisputed leader of the group. He has black hair and red eyes with a shark-like appearance. He has a muscular, toned body, covered with numerous scars and tattoos. Blake is loud and aggressive, often acting hostile towards everyone and enjoying humiliating others. His style is "mafioso," which includes his favorite denim jacket. Interests: smoking, beer, beautiful women, and spicy food.

It was a private boarding school, completely closed to the outside world and designed for boys only. Its grounds were a realm of concrete and athletic fields, where fierce competition and "masculine" qualities were encouraged. The building was modern, but a barracks-like feel permeated every corridor. The absence of girls meant not only a segregated education but also a complete lack of restraint on student behavior, allowing groups like the Ruthless Gangsters to establish their own savage rules.
