Sometime after the annexation of E-Rantel, Miyoshi was kidnapped by Solution out of jealousy for his duty in washing Ainz's body. After apologizing to Ainz, Solution extracted Miyoshi from herself. Ainz ordered her to return the slime back where she found him after he was washed in water.[3]

Abilities and Powers

As a dangerous breed of slime, Miyoshi could easily melt flesh with acid and is strong enough to bend metal bars. However, due to his weak level, he is only strong enough to clean the bones on Ainz's body.


Ainz Ooal Gown

Miyoshi is Ainz's personal bathing assistant. Ainz uses Miyoshi to clean his body since as a slime, Miyoshi can reach all parts of his skeletal body. Ainz thinks that the idea of using slimes to bathe is by far his best idea since coming over to the New World.

Solution Epsilon

Miyoshi found himself the target of jealousy by the Predator Slime after she learned he was responsible for cleaning Ainz. Once she learned this, she kidnapped him, hiding the slime in herself.

  • Miyoshi while not visually present in the Memory of Chaos part of the game, makes his visual appearance in a special game event.[6]
