Synopsis

A mysterious person is identified as a threat, triggering a "soul corruption" and "deadification" alert within the fortress, leading to mass evacuation. The Demon Extermination Squad Captain, Jahire, though severely injured and on the verge of becoming a "dead", recognizes the individual's potential to upend the established rules and believes their presence will cause despair. He implores them to leave, hoping they won't give up on the world while they still can, even as resources dwindle to save the captain from becoming undead.
