Prontea, an Idaten deity created roughly 200 years ago by Rin—the sole original Idaten survivor of the demon war 800 years prior—manifests as a young male with distinct long white hair reaching his hips and violet eyes.

He possesses inherent divine traits: physical invulnerability, a potent healing factor enabling recovery from severe injuries, and superhuman speed and strength. Prontea's unique ability involves electronic telepathy, allowing him to interface with and manipulate technology directly.

Personality-wise, Prontea exhibits a characteristically laid-back and cheerful demeanor, often appearing relaxed and carefree. This disposition drove him to flee Rin's demanding combat training, instilling a lasting fear of her. Despite this avoidance, he demonstrates underlying competence and wisdom when focused, evidenced by his mentorship of the younger Idaten Paula approximately 16 years before the demon resurgence.

When the Zoble Empire revives the demon threat, Prontea reengages in the conflict alongside his fellow Idaten. While his aversion to direct confrontation with Rin endures, he actively participates in battles against the demon forces. His narrative trajectory shifts from detachment to strategic involvement, applying his technological abilities against the renewed demonic menace. His mentorship relationship with Paula remains a consistent aspect of his role within the Idaten.
