Houka Inumuta

Houka Inumuta is one of Satsuki Kiryuin's Elite Four, the Devil's Bureau of Investigation, a bespectacled data analyst who treats every fight as an experiment. He hangs back scanning enemies, muttering statistics, and speaks in the clipped cadence of someone who trusts numbers more than people. Loyalty to Satsuki is absolute, if oddly clinical.

He's the show's resident skeptic-scientist, and the anime leans hard into that: analytical monologues delivered mid-battle, glasses flashing with data readouts, a barely-suppressed delight whenever something breaks his models. Hiroyuki Yoshino gives him a dry, fast-talking energy that makes his obsession with quantifying the unquantifiable both funny and, eventually, quietly poignant.
