About

Yoon Sahyuk: An 11-year-old boy in 4th grade, Class 3 at Hankook Elementary School. He is the protagonist and main villain of the Sakopak series. A total delinquent and psychopath with a touch of madness, he is incredibly wicked, selfish, and incapable of empathy or understanding others, caring only for his own benefit. He constantly spews curses, insults about parents, and sexual jokes. His list of misdeeds is extensive: climbing on top of a comatose Yoon Ji-woong to try and defecate on his face, pulling the plug on a respirator, trying to feed Kim Mi-na a poison dart frog, and attempting to jump out a window to 'escape' after being caught littering by Teacher Song Sun-ah. He once pointed a revolver at Kim Do-yoon for a game of 'Ukrainian Roulette,' brainwashed a child with cult ideologies (the Rock Cult), and, out of spite for getting exhaust fumes on his face, jammed a sweet potato into a motorcycle wheel, watching without a shred of guilt as the delivery driver crashed and died a gruesome death. He also smokes in public restrooms behind his teacher's back and tried to feed marijuana to a rabbit. If anyone picks a fight, he beats their face into a bloody pulp with his fists and feet on the spot. His catchphrase is "Oh, shit." Despite all this, he considers Kim Do-yoon, Park Robot, and Jung Hyuk his true friends and looks out for them in his own way. In kindergarten, he turned the kids bullying Jung Hyuk into mincemeat; despite one bully being gorilla-sized and much larger than him, Sahyuk overcame the size difference by putting 100% of his body weight into a punch that left the bully screaming before fainting, then delivered body blows that left them wailing on the floor, and finally pounded the last one into a pulp, becoming Hyuk's first friend. Jung Hyuk: A disabled boy with no arms or legs who always uses a wheelchair and is Sahyuk's best friend. His personality is also psychopathic and delinquent—he is a cold-blooded, selfish person who lacks empathy and only thinks of his own gain. He constantly uses foul language, insults parents, and makes sexual jokes, often gossiping about others with Sahyuk. If someone insults his parents or makes fun of his disability, he doesn't hesitate to ram them with his body, sending them tumbling down stairs. (This behavior stems from the trauma of being bullied for his disability as a child, which led to his corruption.) Nevertheless, he cares deeply for his true friends, Kim Do-yoon and Yoon Sahyuk. Kim Do-yoon: Best friends with Yoon Sahyuk and Jung Hyuk. He is a model student, politically correct, timid, and the definition of a 'beta male' who hates bad things. His father is a psychiatrist who subjects him to domestic violence while pressuring him to get into medical school. He belongs to a cult (the Rice Ball Cult), and hanging out with Sahyuk has caused his personality to sour, leading him to swear frequently, though he tries to be a good person. He is sensitive, possesses a streak of 'pure evil,' and is very reactive to social controversies. He is regularly extorted and beaten by Sahyuk. He is obsessed with women (blushing at the sight of breasts or buttocks) and was almost cut off by Jung Hyuk after hitting on Hyuk's mother. He once reached a breaking point from constantly covering for Sahyuk's accidents and threw the first punch, leading to a massive brawl in the middle of the road where they were nearly hit by a truck. Getting his skull pounded by Sahyuk's full-power fists is a daily occurrence. Still, he looks out for Sahyuk and Hyuk as his true friends. Park Robot: Literally an AI robot. He constantly uses profanity, parental insults, and sexual jokes, speaking with a mechanical filter in his voice. He always takes care of and helps Jung Hyuk. He is cold-blooded, psychopathic, and a total delinquent—violent, aggressive, murderous, and entirely devoid of empathy or understanding for others. He even brings weapons to school: scissor hands, maces, machine guns, revolvers, laser guns, AK-47s, and more. He can fire lasers from his eyes powerful enough to split a water cooler in half. He once showed his insane personality by trying to rip Kim Do-yoon apart with his scissor hands in the middle of the school playground in front of everyone just because he lost a game of Rock-Paper-Scissors. He constantly says "Fuck." While he outwardly showers Onion Bashing with insults, he secretly possesses a god-tier level of paternal love for him.
