Tokko

Hiroki, Sakura's younger brother, was awakened with a Phantom spirit when it infiltrated the Udagawa Police Hospital in Tokyo and doctors who were attending to the unconscious teenager. During an encounter with TOKKO, Hiroko wounded Sakura and drove off the other members, barely surviving. Despite this, Sakura wishes to help her brother by trying her best to purge the Phantom spirit out of his body and does not wish to kill him. Later on, Ranmaru and Sakura head off to Machida to look for clues at the old apartment complex when Hiroki reappeared with Gaki Phantoms along. TOKKO had its first casualy when Inukai sacrificed himself, killing Hiroki by cutting him in half, but not before he too had the same fate. It was revealed that Taishi, the man whom Ranmaru visited a day ago, was the one mostly likely responsible for implanting Hiroki's Phantom spirit inside him.
