Strength and powerful shoulder barge[]

As the larger twin brother, he uses brute strength to tackle or plough through defenders. It is a common skill in the entire Ryoin High team, except his twin brother.


His decoy is based on his size and broad shoulders to shield his brother.


  • Dislikes: Anime because Sekito is obsessed with it.
  • He also honed his own set of skills on the playground, but his is based on absorbing his brother's hits and power moves.
