MAD TRIGGER CREW (abbreviated as M.T.C) is the Yokohama Division representative rap team, consisting of navy veteran Rio Mason Busujima, policeman Jyuto Iruma, and their leader, yakuza Samatoki Aohitsugi.


The crazy criminal group that controls the Yokohama area as both champions of justice and malice, destroying other teams with their fighting spirit the moment they’re faced with their lyrics.[1]


After a semi-successfull drug bust, Jyuto Iruma was approached by Samatoki Aohitsugi who offered him to form a team together. Jyuto accepted the offer and built a mutually beneficial partnership with Samatoki and his clan. While working on the case, Jyuto met Rio Mason Busujima and saw him as a potential third member of their team and decided to recruit him, so they could participate in the Division Rap Battle.

Despite initial hostility between Samatoki and Rio, they joined forces after they were ambushed by a group of criminals. Indebted to Samatoki and Jyuto for helping him against criminals, Rio joined their team, and together they formed MAD TRIGGER CREW to represent Yokohama Division.

  • MC Name: Mr.Hc (Mr. Hardcore)
  • Occupation: Yakuza
  • Rap Ability: Counter Blow
  • Description: A former member of The Dirty Dawg and the second-in-command (wakagashira) of the yakuza clan Katengumi, based in Yokohama. He has a perpetual frown on his face and is quick to start a fight if something displeases him, but he would never raise a hand against a woman. He even became a yakuza for his beloved little sister, Nemu Aohitsugi. He treasures the good luck charm she made for him. He and Ichiro Yamada from Ikebukuro Division hate each other’s guts.

  • Rap Ability: Prison
  • Description: An active-duty police sergeant in the Organized Crime Unit of the Yokohama Police Department. A vicious police officer familiar with the world of the yakuza, willing to investigate through illegal measures, though he hates the illegal drugs that led to the death of his parents and colleague. He will use any means to achieve his goals. He holds a mutually beneficial relationship with Samatoki Aohitsugi of the Katengumi.

Rio Mason Busujima

  • MC Name: Crazy M
  • Occupation: Ex-Navy
  • Rap Ability: Shelter
  • Description: A former Sergeant First Class of the Naval Forces and the member of the Special Extermination Operations Unit. Half-American on his father's side, and half-Japanese on his mother's. He speaks and behaves as if he were still a soldier. During his time as a naval officer, he respected rank above anything else. For example, if a superior told him that white was black, then white was black. In dire circumstances, he shows no mercy to his enemies. That being said, he's calmer in peacetime and likes to help people. His hobby is cooking food that serves a practical purpose. His skills are those of a professional, but for some reason, Samatoki and Jyuto fear him.


Heavily inspired by West-side hip-hop, MAD TRIGGER CREW's style is brutal and violent, given to members being connected to the criminal underworld and the military. Their songs usually cover dark themes, such as crimes, justice, and death. Also, one of the most important themes for MTC is loyalty, as Samatoki, Jyuto and Rio use their individual power to amplify each other.
