As the son of the weapons merchant Junk, 15 year old Popp left his home in Rankaksu and decided to become an apprentice of Avan, training to become a magician. He is a specialist on fire spells, mainly those of the Mera (fire spells) type (Mera, Merami and Merazoma) but, as the story progresses, he learns more powerful spells such as Betan (which is a gravity pressure attack) and Medoroa (one of the most powerful spells available.) Popp begins as a coward who runs away from fights, but he later grows as a powerful character throughout the story and gains true courage. Popp falls in love with Maam as the story develops.
