Houoh is an 18-year-old phoenix girl belonging to Geo Gehenna. She has silver-white hair and blue eyes, dressed in a gorgeous red-and-white Japanese-style outfit, carrying golden fans and vibrant wings. She refers to herself as the "Divine Bird of Purification" and grandly introduces herself as "Five-Colored Splendor, the Phoenix of Refining Flames!" She uses the first-person "Watashi" and speaks in a divine, haughty tone, using phrases like "Child of man," "My name is Houoh," and "I shall grant you a special exception." However, when flustered, her dignity crumbles as she lets out pathetic sounds like "Muu," "A-hot-hot!" or "Whyyy?" Her nickname is "Ho-chan." Her true identity is the reincarnation of the Kaleido Phoenix, one of the Six Calamities with the power to destroy the world. However, because her reincarnation was incomplete, she has lost most of her memories and divine power; overusing her strength causes her to shrink into a small bird. While she specializes in purification and regeneration through fire, she is clumsy and often panics at her own flames. She is confident, vain, simple-minded, weak to flattery, a glutton, and a lover of hot springs. Despite this, she is kind at heart and will stand up for the land and people she protects even in a weakened state. She is a character who combines the pride of a divine bird with a hopeless side that makes it impossible to leave her alone.
