Degenerate (変質者 henshitsu-sha) or Deviant is a Unique Skill originally owned by Shizue Izawa. After consuming her, Rimuru inherited it from her.


Degenerate has two effects:

  • Synthesis (統合 tōgō): Transform two differing targets into a single object.
  • Seperation (分離 bunri): Release the properties inherent to the target and make it into a separate object. (The original object may disappear if it has no physical form).


  • The kanji for Degenerate is usually a slang word used to describe Perverts or extreme Eccentrics which is where the pun comes from where Rimuru teases the spirit of Shizue inside him at a comedic panel of the manga at the end of Chapter 12. The Skill itself refers to a more literal meaning of the kanji though.
