Shingo Hojo, a former soldier burdened by profound personal trauma from his wife's death on their wedding day, initially joined the Good Thunder team with reluctance. He served as the primary pilot of the King Arrow component, frequently assuming the role of tactical leader during missions and commanding the main torso section of the combined mecha formations.

Decades after the primary events, he reappears as an older man whose enduring loyalty and protective instincts remain sharp. When Remy Shimada suffers a life-threatening accident, he rushes to the hospital alongside former teammates and adversaries, revealing lasting bonds. During her coma, he actively enters her subconscious, participating in her psychological battle against death and revisiting pivotal shared experiences.

These include a critical event where the team was trapped in a mysterious desert town receiving prophecies of imminent death. Within this shared dreamscape, he collaborates in confrontations against supernatural threats, demonstrating sustained combat skills and seamless teamwork long after his active service. His interactions showcase a cultured rapport with Leonardo Medici Bundle, a brotherly dynamic with Killy Gagley, and a complex history with the former Dokuga generals, now united in concern for Remy.

His characterization consistently emphasizes resilience, leadership, and deep commitment to comradeship. The desert town sequence highlights his defiant refusal to accept fate passively, while the hospital vigil underscores unwavering support during crisis. His physical capabilities are evident in collaborative combat, such as a bar fight where he fights back-to-back with Killy. His presence within Remy's visions reinforces their shared history and collective identity as warriors confronting mortality.
