Sputter

is the name of the sentient fireball that Maki Oze creates using her abilities as a Second Generation.

Usage
Pusu Pusu takes the form of a small floating fire-blob that generates the sound of crackling fire. Though the technique isn't lethal, it can knock down and subdue an individual. It can used defensively, by utilising the flames of an enemy to become this. With enough flames, the technique can generate produce a gigantic, horrendous-looking fireball.

Trivia

 * The creature's appearance is inspired by Maka Albarn's (who is a main character from Atsushi Ōkubo's previous work) soul.
 * Pusu Pusu ("プスプス") is onomatopoeia of crackling fire.
 * The huge fireball creature, produced using Pusu Pusu and Third Generation flames, can somehow bleed, despite being made out of fire. This is most likely for comedic effect.
