Domptage : Évolution générale, régression unique

Expelled by the Collins family, illegitimate child Miles Collins has rare beast-taming talent but is too poor to form a pact with even a lowest-tier spirit beast. Humiliated by Ryan Collins and Sophie Grant, he awakens the Ultimate Beastmaster Reversion System. While others evolve, he uses ancestral reversion to turn a green caterpillar into the Void Azure Dragon!
