An otaku who was simply a Kamen Rider fan happens to obtain Kamen Rider powers through a chance encounter, then amplifies them to a terrifying degree.
Kuuga's Ultimate Form can destroy heaven and earth. OOO's Ice Combo can return the world to an ice age. Kabuto's Hyper Form can pierce through the Earth with a single shot. W's Extreme Form can unleash a light brighter than the sun...
Most importantly, he can transmigrate to different worlds and win over beautiful women.
P.S. This is a crossover novel with a Kamen Rider theme. The protagonist's powers are mainly based on Kamen Rider, but he'll also have other powers, since he can't rely on Kamen Rider powers alone when he goes to other worlds.
