Bullied outcast Rudo finds respite in repurposing trash, until a terrible tragedy changes his life forever.

Cast into the Pit, Rudo is saved by the mysterious Enjin who may not have his best interests at heart.

After being introduced to Cleaner HQ, Rudo follows Riyo on a job to learn the business.

Enjin is a Giver, a being who can give life to things and draw out their power. Ludo, who has also awakened to his power as a Giver, is scouted by Enjin to join an organization called the Cleaners, which fights against the Spotted Beasts born from garbage. Ludo accepts the offer in order to find a way to return to the Heavenly World where he has lived until now, but he suddenly gets into a fight with his trainer, Zanca.
