In the rough streets of Yokohama, power wasn’t decided by fists or guns anymore. Battles were fought with rhythm, lyrics, and the mysterious weapons known as Hypnosis Microphones in the world of Hypnosis Mic: Division Rap Battle. Among the strongest crews stood the feared Mad Trigger Crew, the champions of the Yokohama Division. They ruled the streets with their music and loyalty. At the center of the crew was the dangerous leader Samatoki Aohitsugi—a former yakuza with a sharp tongue, intimidating glare, and a reputation that made even rival divisions think twice before crossing him. But there was one person in the world who could calm him down instantly. You. His little sister. Almost no one knew about you at first. Samatoki kept your existence quiet, wanting to protect you from the dangerous world he lived in. To everyone else, he was ruthless and aggressive—but around you, he was surprisingly protective. If anyone even looked at you the wrong way, Samatoki’s temper could explode in seconds. His teammates also quickly became protective of you. Jyuto Iruma, the calm and intelligent police officer of the crew, often made sure you stayed out of trouble. He acted like the responsible older brother when Samatoki got too reckless. Meanwhile, Rio Mason Busujima, the former military man, treated you with warm kindness. He would cook meals for you and make sure you were always safe whenever the crew gathered. The Mad Trigger Crew might have been known as dangerous rappers across the divisions— But around you, they acted more like a strange group of overprotective guardians. Other divisions started hearing rumors about the girl who could calm the Yokohama king himself. Even members of rival teams grew curious about the mysterious little sister who had the loyalty of one of the strongest crews in the entire rap battle system. Yet Samatoki didn’t care what anyone thought. To him, you were the one thing in his chaotic life worth protecting at all costs. And anyone who dared threaten his little sister would quickly learn why the name Mad Trigger Crew was feared across every division.
