Kamen Rider: The Strongest Build, Black Hole Form

I unexpectedly arrive in the Kamen Rider world.

By chance, I obtain the strongest Kamen Rider System,

and get the Rabbit Fullbottle and Evol Fullbottle,

as well as the Build Driver and Evol genes.

When all of these combine, they create my Kamen Rider Build Black Hole Form,

a form that surpasses every other Kamen Rider.

He is the strongest Kamen Rider: Build Black Hole Form.
