(Dubbed) Trash Dragon Ate the World!

The Story

Summoned as a tiny dragon by a pretty girl, he suffers a brutal betrayal when she rips out his core and discards him in the trash. A school beauty finds the abandoned creature and forms a new contract with him. As a devastating beast tide sweeps through the area, everyone else flees in panic, but he chases the threat head-on. Through this intense battle, he undergoes a massive evolution. His former summoner now kneels before him in shock, questioning if this powerful entity is really the F-rank trash she threw away. Yet, when she attempts to reclaim him, his new master watches the interaction with a knowing smile.
