The First Generation of Ultra Heroes

Shin Hayata, a member of the Scientific Special Search Team (referred to as Team Kot), was patrolling in a plane when he discovered a red sphere chasing a blue sphere. The red sphere accidentally hit Hayata's plane, and Hayata died as a result. Hayata, who had already sacrificed, was sucked into the red sphere, met Ultraman from the M78 Nebula, and learned that he had come to Earth to pursue the space monster Bermuda. In order to compensate Hayata, Ultraman decided to become one with him and give his life to Hayata. As a result, the two began to cooperate with the scientific special search team to launch a fierce battle to defend the earth against monsters and cosmonauts.
