Symptom of Synesthesia

Among the crowd, Keigo keeps clowning with the host's pose until Mizuiro is whisked away by two admiring women, and Sado quietly asks whether anyone else hears the strange cry. Ichigo does, and Rukia identifies the source as a bound spirit tethered by chains to the ruined building. When Ichigo notes that it resembles a Hollow, she clarifies that it is a plus caught partway through that transformation, a half-formed creature not yet fully corrupted. Nearby, the wailing leaves Karin queasy and unsettles Tatsuki and Orihime as well.

Rukia lays out the underlying mechanics. A Hollow's central hole marks the loss of the heart that once anchored it, and its mask hides its raw instinct from the world; a spirit that still keeps its center needs neither. Death severs a soul's chain of fate, and those weighed down by regret stay shackled to whatever they cannot release, spirits bound to people or, as here, bound to a place. This particular ghost rages that the hospital was stolen from him, having schemed to inherit it before his younger brother received it instead.

An announcer silences the audience and counts down to the emergency broadcast, framing the abandoned hospital as a site tormented by an evil spirit. Don Kanonji drops from a helicopter and parachutes down to greet the crowd, prompting Rukia to gleefully copy his signature routine. Ichigo urges that they perform a soul burial at once, but Rukia insists the spirit is months away from turning and shows no present pain, so the ritual can wait. That caution proves misplaced when Kanonji abruptly produces his so-called Super Spirits Stick and rams its tip straight into the spirit's exposed hole, horrifying both Shinigami.

This chapter delivers key exposition on Hollows, the chain of fate, and the distinction between place-bound and person-bound spirits, terminology that recurs throughout the series. It was folded into the anime's tenth episode, Casual Soul Realm Assault Trip! The Viz title matches the original, Symptom of Synesthesia, and the chapter belongs to the fourth collected volume.
