Shigatera acts as second-in-command of the Pirates Guild, operating directly under its leader, Pico. He demonstrates unwavering loyalty to Pico, consistently appearing alongside the guild leader during operations and supporting all plans. Their partnership extends beyond two years of shared experiences within the game environment, establishing a foundation of mutual trust and familiarity. The Pirates Guild systematically steals virtual items from other players, a practice leading them into direct conflict with the Akabane Family. Shigatera participates in this guild war, contributing to escalating tensions. Following an encounter with the Black Bird entity, Shigatera logs out of the game. Subsequent to this logout, the Black Bird manifests physically in reality. Shigatera witnesses the entity violently kill Hana Kamuro via cranial explosion, demonstrating its reality-altering capabilities. His narrative function transitions from active participant in virtual conflicts to observer of the emerging real-world threats originating from the game. His known background remains confined to his guild role and partnership with Pico.
