Biz O'Naill thrives in San-Teresa’s shadows as a black market dealer and proprietor of the strip club Lady Chapel, cloaking his operations beneath the guise of a priest. His gaunt, towering figure cuts a striking silhouette, marked by a waxed mustache, full lips, and a hairless scalp. Red quad-lensed sunglasses obscure his gaze, paired with a gold crucifix, a broad black hat, and priestly robes—a calculated fusion of sacrilege and sanctity.

Though he masquerades as devout, his true vocation thrives on manipulation, theft, and double-dealing. As Detective Kei Matoba’s clandestine informant, he trades secrets on Mexican smuggling rings and arcane contraband like fairy dust, skirting legal repercussions while entrenching his underworld influence.

Lady Chapel’s neon-lit facade masks his illicit trade, though the roots of his duplicity remain shrouded. A persistent shadow in the narrative, he maneuvers between crime and law, exploiting his holy veneer to puppeteer rival factions—his past, motives, and broader legacy unspoken, anchored solely to his role in the anime and light novel’s tangled web.
