Part-Time Knight Boss, Starting as Ark-One

On the world of Earthstar, battle armor reigns supreme!

Lu Yu transmigrates into this world, only to find himself in a rather grim situation.

Though he awakens as a Tech Armor Master, he has neither the money to build anything nor a decent blueprint.

Luckily, the Kamen Rider BOSS System arrives!

As long as he connects his consciousness to a dungeon, he can enter it as a BOSS and open a hidden dungeon. By killing the adventurers who challenge him, he can obtain the equipment and materials they drop!

From the start, Lu Yu hits the jackpot, drawing Ark-One and obtaining the blueprint for the Zero-One suit.

From then on, a Kamen Rider dungeon BOSS becomes active in dungeons of every level, stripping adventurers of everything they own.

Adventurers around the world are instantly set ablaze, all joining the plan to take Lu Yu down!

When dungeons open worldwide, Lu Yu puts on a golden belt and makes a powerful entrance through the river of time.

"The most benevolent! The most virtuous! The supreme! The strongest king!"
