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.

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.

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

The Cleaners go on a job to save another Sphereite who survived the fall. Rudo tags along to learn more.
