Midnight's Quirk allows her to put targets to sleep by exuding a sleep-inducing aroma from her body.
The aroma is described as being more effective on males than females, giving Nemuri an obvious advantage against men.
It is possible to avoid the aroma by simply not smelling or breathing it in. 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.
- The kanji used for this Quirk literally mean "sleep fragrance" (眠り香 Nemuriga?).
- A somnambulist is a sleepwalker.
