Ultraman: The Ultimate Sixth Ranger

[Original Ultraman + original monsters + villains]

Bai Yanchuan is a senior in Class Three at Little Fat Sheep No. 1 High School. Simply because he is close to a girl named Ye Jingwen, a large truck inexplicably sends him flying on his way home from school. When he wakes up, he finds himself in an unfamiliar city, and a System has been bound to him. But the further things go, the more he realizes something is wrong, because all sorts of monsters that were never supposed to exist have begun appearing. (For details, please read the main story.)
