My F Rank Cat Devours WorldsEpisode 21

Cael Voss, an underdog Beastbinder, is betrayed by his girlfriend Lyra Ashford at Ironhaven Academy—she frames him for stealing her Blazing Dragon, leading to his expulsion. Desperate yet undefeated, Cael awakens the Divine Beastbinder System, upgrading his "trash" Shadow Cat to the world-shattering Void Fang. As Lyra climbs the ranks by clinging to power, Cael rises silently from the bottom. Their fates collide again at a World-Breaker Relic Site, where the once-scorned nobody confronts the arrogant traitor, ready to reclaim his glory and settle old scores.
