Daisuke Honda commands Special Weapons Enforcement, a government task force hunting psychics. He orchestrates a bombing assault on a psychic research facility with Russian military aid to eliminate the Kirihara brothers, an act that severely traumatizes Yuya Kuroki and provokes him to aim a weapon at Honda. Honda displays consistent ruthlessness toward children, imprisoning young psychics and ordering criminals to mutilate them as punishment for abilities like singing. He pursues the child psychic Masayuki relentlessly.

During the dimensional fusion crisis, Honda witnesses the singularity point heralding global destruction and violently chokes Kimie Kobayashi before throwing her aside. Convinced that killing the Kirihara and Kuroki brothers will prevent apocalypse despite warnings of futility, he attempts to execute Naoto Kirihara and Takuya Kuroki. This choice triggers his demise when Kimie Kobayashi retaliates by shooting him for his assault, ending his tenure as SWE commander.
