I recommend " Country of Light: The Beginning of a Cloud Monster Raising System " to you. This light novel tells the story of the protagonist Lin Chen transmigrating to the Ultraman World and becoming an Ultraman who is about to join the Universal Garrison. After awakening the Cloud Monster Raising System, Lin Chen's strength has increased through the Cloud Monster Raising System. The storyline is full of imagination and the unique elements of the Ultraman World. I hope you like my recommendation. Muah!
