Tyran 94

A world in ruin. A destructive, monster-worshipping cult running rampant. Only one being can save us all, Ultraman. We follow MC as he traverses the world, only looking out for himself. He's fallen into a state of solidarity, but it's all shaken up when he meets an old man who is being chased by a group of RDB goons. Will MC help him? And why does RDB want him? Does he have something to do with the salvation of the world?

When the SSSP, a group made up of young people looking to do good in the world, is tasked with investigating a possible giant monster, one of their own, Takeshi, sacrifices himself in order to save one of his teammates. Luckily for Takeshi, he is saved by Ultraman. Now the two are bonded as one and are tasked with taking care of the monsters plaguing the world at large.
