Akari Hiyama, also known as Princess Inferno, was one of the main characters in Mahou Shoujo Ikusei Keikaku. She was a student at high school who had previously been part of a club but had to withdraw due to an injury she suffered in the past. Despite this setback, Akari possessed a distinctive guandao that could emit heat and evaporate large amounts of water instantly. This weapon also had enough power to inflict harm on other Magical Girls.
