Kamen Rider Ryuki: Dawn of the Void

[A Kamen Rider Ryuki fanfic, revised edition of The Shattered Mirror of Humanity. Some plot points and character settings have been changed. Not a power fantasy, no transmigration, one female lead.]

He only wanted to be an ordinary boy.

But fate thrust him into a deadly battlefield behind the mirror: a survival game between Kamen Riders.

Here, fighting is the only way to stay alive.

When kindness becomes a luxury and an ordinary life an impossible dream, can he fight his way through the brutal Rider War and carve out a bloody path to tomorrow? If you don't fight, you can't survive. But does fighting mean losing the humanity he started with?
