Hōko Sanzō, a direct descendant of Tang Sanzang, is a 17-year-old honor student at Oshaka Academy in Kamakuland. She serves in the "Tatemae Trio," a group assigned by Headmaster Ochaka to gather scattered copper puzzle plates and complete the Oshaka Puzzle board for the school’s honor.

Outwardly pure and beautiful, her true nature reveals arrogance and a mean-spirited disposition. When angered, she displays violent tendencies that starkly contrast her elegant facade, yet she wields considerable physical strength capable of overpowering thugs.

For puzzle-collecting missions, she dons distinctive light white attire and rides a robotic horse supplied by Headmaster Ochaka. Her travel relies on Omonki, the principal’s monkey-shaped mascot robot, which facilitates spatial teleportation to puzzle sites.

Though positioned as a protagonist, she avoids active combat, delegating battles entirely to Itadakiman. Her role remains passive: she typically arrives post-conflict to secure puzzle pieces before departing, underscoring her detachment from direct heroics.

Her dynamic with protagonist Kusaku Magota proves complex; he expresses preference for her over the rival "Nizuzumon Trio," reflecting her perceived status, yet she maintains general indifference toward him.
