Shikanoin Heizou is an extraordinary young detective from the Tenryou Commission in Inazuma. A prodigy renowned for cracking unusually complex cases, he is the last hope for minor, major, or mysterious incidents. Admirable and principled, sometimes more so than his peers, he fights with Anemo-infused fists and kicks using a catalyst in melee style. His Heartstopper Strike delivers powerful punches that build Declension stacks for increased damage, and he excels at triggering Swirl reactions as a damage dealer and driver.
