Flare

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

Usage
When combined with the flames of the Third Generation and Pusu Pusu, the technique can produce a gigantic, horrendous-looking fireball.

Trivia

 * The creature's appearance is inspired by Soul Evans's (who is a main character from Atsushi Ōkubo's previous work) soul.
 * Mera Mera ("メラメラ") is an onomatopoeia of burning 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.
 * In the subtitles, as well as English dub, Mera Mera’s name is changed to Flare.
