(This is a fictional world closely resembling our own. Any similarities are purely coincidental.)
Duan Yu loves collecting Ultraman transformation devices. By chance, he buys an officially licensed Ultraman Zero device. At just that moment, a 48-meter-long, fifty-thousand-ton octopus appears off the coast of Country R! Meanwhile, Duan Yu’s hairstyle, habits, and physical fitness are all quietly starting to change... (This is my first time writing a book. I’ll do my best to avoid mistakes, so please go easy on me!)
