Fabron Lynn rescues a lightning-type mutant called Lightning Marten, and a contract auto-forms naming him its contractor. The system explains any animal with mutation potential can be raised to unlock latent powers and eventually become world-destroying beasts; when bonds reach maximum the creature can transform into a higher form, suggested to be human. After completing the beginner rescue quest Fabron claims the starter pack. He jokes to his parents, "I'll bring you many daughters-in-law," then vows to use this power to find the truth. The episode ends with him poised to deepen the bond and test the transformation.
