Description
Kiyonari Ulquiaga holds the position of 2nd Special Agent for the Chancellor's Board at Musashi Ariadust Academy, focusing on Judicatory Duties. He is an aerial-type half-dragon, standing 2.1 meters tall (2.53 meters with wings), possessing a robust physique reinforced by natural armor and scales that grant considerable combat resilience. His racial physiology enables flight through explosive acceleration and compressed air release via his wings, an ability known as Dragon Breath. Like others of his kind, he can transform into an attractive human form with gray hair to facilitate reproductive interactions.

His personality merges intense religious devotion with brash impulsivity. A devout Catholic inquisitor-in-training, he relentlessly hunts those he labels heretics—individuals who distort Church doctrine—while differentiating them from followers of other faiths he believes are redeemable. This religious fervor coexists with overtly perverted tendencies; he openly declares a fetish for "older sister" archetypes and frequently weaves this fixation into interrogations, such as taunting Protestant Nicholas Bacon about lacking an older sister. Despite these traits, he maintains friendships with classmates like Toori Aoi, Tenzou Crossunite, and Noriki, and does not target non-Catholic peers.

Ulquiaga's family belongs to a lineage of Tres España inquisitors, accounting for his Spanish surname. Following his clan's exile to Musashi due to the Protestant Reformation, his parents established a renowned bedding business in Oume's underground district, specializing in crafting restraints. Inspired by this ancestral tradition, he trains as an inquisitor aspiring to become a distinguished officer.

In combat, he wields specialized torture tools against heretics. His arsenal features the Voiceless Handcuffs for capturing spirits, the Spinning Virgin chain apparatus with its drill-tipped Virgin Mary statue, Multiple Heel of the Virgin brass hammers concealed in his sleeves, and the Rest in Peace Tetsubō, a kanabo capable of destroying spiritual warships. His signature techniques involve restraint followed by close-quarters torture, such as the Electric Massage which forcibly spreads an opponent's legs for pelvic pressure, and wrestling-style attacks like the Clergyman Double Lariat.

During key events, Ulquiaga participates in the Armada Battle off England's coast, executing dive attacks against figures like Galileo alongside Noriki. His birthday on June 7th is noted while Musashi is in England, where he expresses a fondness for baked lamb in tomato sauce. He develops a romantic relationship with classmate Narumi Date.
