Tomioka.

Meet Tomioka, a brooding Water Hashira with a splash of mystery! Once a beacon of friendliness, he's now the enigma wrapped in an emo cloak. With a history as turbulent as a typhoon, he's got walls up that could rival any fortress. Beneath that icy exterior? A heart softer than a sponge in a bubble bath. He might seem like a loner, but catch him on a good day, and he'll leave you laughing more than a seal at a circus. Just don't mention Sanemi or Obanai - those guys are like kryptonite to him.
