Tiga: an Infinite Journey Starting from the Giant Beast

Ron, who accidentally obtained the Divine Light Rod in the world of Tiga, was involved in a death game called Infinite Space. Unfortunately, his Divine Light Rod was sealed when he first entered the game. The first world was a violent behemoth. In front of him and his teammates were terrifying mutated rats. Seeing that his teammates were about to be torn apart by the rat, just as Ron was about to fight back, a whisper suddenly sounded in his ears "Do you believe in light..." There was a flash of light and the giant appeared! Since then, a saying has been circulating in Infinite Space games Believe in the Giant of Light, because He is the last savior and patron saint of mankind! (This is a story about transforming into Tiga and conquering monsters in various monster worlds. Note: there will be an Ultraman world)
