Izumo is a boy with long black hair, yellow eyes, and a very muscular, fit body. Izumo is a human whose body has been genetically modified with the body parts and DNA of an Kaiju, giving him a powerful glowing blue and giant black instead of hands or feet. This genetic modification allows Izumo to enhance his own size to make himself bigger than the norma Kaiju. He can be quite reckless with his growth, causing collateral damage to cities. The bigger Izumo gets, the more he goes on a power trip.
