A Knight: Devouring and Evolving from Lockseeds!

Reborn as an ordinary Lockseed.

Ye Nan is astonished to discover that he has entered a vast world where all the Heisei Kamen Riders have merged. He himself has become a Lockseed, with the god-level abilities of infinite devouring and infinite evolution.

With the talent to evolve without limit, he can be used by all kinds of Kamen Riders, granting them strange powers and a brand-new, overwhelmingly powerful form: World!

Sougo, Tsukasa Kadoya, Gaim, Dan Kuroto, and others have all been his Hosts.

But every Host ends up either dead or crippled.

Some call me the "Seed of the World," Hephaestus, and sing my praises day and night, for anyone who wields me gains the power to control the world.

Some call me "Pandora's Box," because using me makes it impossible to know what terror awaits.

But most call me the "Seed of Curses," the "Seed of Demons," because when I appear in the world, bloodshed follows and calamity descends.

I have countless titles, yet all are held in awe.
