Kagi-P

Known by the alias Kagi-P, he served as the unseen musical architect of the virtual idol μ and a core figure within the Oshitsu Gakushi. Concealed inside the closed loop of Möbius as an ordinary high schooler, his cover inadvertently cracked when he appeared at both the graduation and entrance ceremonies simultaneously—an anomaly that sparked the protagonist's first suspicion about the world's fabricated nature. Shaken after a pivotal confrontation, he severed ties with the group and aligned himself with the Homecoming Club, driven by a longing to escape back to reality. Beneath his trademark blend of sharp sarcasm and overly courteous demeanor lies a quietly exhausted soul who has all but surrendered hope in the world he once left behind.
