Somnambulist ( (ねむ) () Nemuriga?) is the Quirk used by Midnight.


Somnambulist allows Nemuri to put targets to sleep by exuding a sleep-inducing aroma from her body.

Somnambulist is described as being more effective on males than females, giving Nemuri an obvious advantage against men.[1] Regardless of that, those who breathe in enough of the aroma will eventually fall into a deep slumber, making it really difficult to confront Nemuri at close range.

It is possible to avoid the effects of Somnambulist by simply not smelling or breathing the aroma in.

In the anime, the mist that represents the Quirk's aroma is colored violet.


Somnambulist makes Nemuri an efficient referee for competitions, as she is able to prevent dangerous plays by just putting the violating contestant to sleep.

For legal reasons, Nemuri is forced to wear a bodysuit to counter her provocative costume, which might hinder the effectiveness of her Quirk as she must rip it out first to release her aroma. She stated as much in an interview where she said she is trying different thin materials in her costume she can tear easily to release her fragrance.


  • The kanji used for this Quirk literally mean "sleep fragrance" (眠り香 Nemuriga?).
  • A somnambulist is a sleepwalker.
  • This Quirk works similarly to Gas. Unlike Gas however, Somnambulist doesn’t have toxic properties, has no direct effect on the user, and isn’t potent enough to put someone into a coma.
