Kamen Rider: Prince of Shadow

(The new book "Max's Civilization Observation Record" has been released! Begging for support)
When a lonely soul wakes up again, what he sees is a weirdo wearing a metal mask.
"Shadow Moon, Kamen Rider BLACK, no, now it should be said that you are the enemy of RX! I will help you revive, and together with my Commander-in-Chief of the Cressi Empire, Jagu, defeat RX!"
The weirdo who calls himself General Jagu said.
The alien who inherited Shadow Moon's identity set a small goal before he had time to think about his future decision - to have a motorcycle of his own first.
As for where the motorcycle came from... it's obvious.
