  • Ki Manipulation: Yo-ki manipulation, that is.
  • Out of Focus: He seems to get the least amount of focus out of the 4 main characters and he's yet to use his sorcery effectively in the Shadowside anime. Subverted in episode 13 when he gains the Yo-kai Watch Animus, after this, there are noticeably more episodes, resolving around him.
