Mouse Hairball

The user transforms their spit into a flaming ball of hair that assumes the shape of a mouse engulfed in flames, which then continually splits into individual and similarly ablaze hairs. These flaming projectiles pursue the intended targets before exploding, once they come into contact with an object.

Trivia

 * This attack appears to be a nod to the Fire rat, a yōkai of Asian mythology, notably mentioned in The Tale of the Bamboo Cutter.
