Tekuni Depagā serves as the central protagonist in the original anime film and its manga adaptation. Hailing from the far east, she belongs to the wazabito—individuals who train heart and spirit to manifest objects through concentrated willpower, where effectiveness scales with determination. Her journey spans the world as she trains to master these abilities and become a fully realized wazabito combatant.

She sports distinct pigtails and a consistently scantily clad costume, typically form-fitting outfits that highlight her physique during action. Primarily a sword fighter, she blends materialization skills with traditional swordsmanship in combat.

An owl companion named Fukku Rō (alternatively Huk-Ro), identified as an owl of knowledge, accompanies her travels. During her journey, she rescues a young girl named Ruri after Ruri is separated from her father Cient and attacked by a massive humanoid weapon called an Oxylic.

Characterized as a wandering warrior, Tekuni moves through dangerous situations while aiding those in need. Her encounters forge friendships amid confrontations with adversaries, focusing her role on combat assistance through wazabito skills during isolated incidents.
