Shin is Captain of TPC's moon base Garowa. One day, Garowa is attacked by Menjura, with he, Coporal Kishinaga and Okabe are the only survivors, Menjura took the forms of Shin and Kishinaga, cocooning them and using their identities to frame them for destroying Garowa. Once the Menjura arrived on Earth in the forms of the Captain and the Corporal, they began taking the forms of several other people, including the Inspector General, the Staff Officer, and even Captain Iruma, Rena, and Daigo of GUTS, all while GUTS all while GUTS themselves began to grow incresingly suspicious of the impostor's choice of actions. Once Obake (a survivor of Menjura's attack on the moon base Garowa) arrived at GUTS's HQ, he exposed the Menjuras' true identity, forcing the surviving Menjura (still in their disguises) to escape with a hijacked jet from GUTS. Daigo transformed into Ultraman Tiga and chased down the jet with the Menjura aliens inside of it. After blasting the jet and forcing it to crash in an Oil Refinery, the Menjura combined into its monstrous giant form, blasting Tiga down as well. The twin Menjuras quickly overpowered Tiga with its array of weapons and double teaming, but once Obake and GUTS arrived to assist the Ultra, the odds were evened for both side. Ultimately, both Tiga, TPC, and GUTS managed to destroy the Menjura with a combination of Tiga's Zeperion Beam, and the gunfire of GUTS and TPC. After Menjura was destroy, Shin and others depart for the moon to reconstruct the Garowa. He also mails for Captain Iruma invites GUTS visit them on the moon after recontruction is finished.
