Fairy Tail - 100 Years Quest - Episode 15

In Episode 15, the destruction of the last orb meant to seal the Forest Dragon God Aldoron backfires, causing him to break free from his restraints and awaken. The white mage who sought to exploit Aldoron's power realizes she was deceived by Selene, the Moon Dragon God. After the spell is broken, the members of Fairy Tail regain their magic and consciousness.

As Aldoron awakens, the cities built upon his body begin to crumble, and their inhabitants are revealed to be "seeds"—beings meant to nourish the dragon. God Seeds, extensions of Aldoron, emerge to eliminate those who do not belong to him by reading their thoughts and transforming into powerful forms drawn from the memories of the Fairy Tail members.

Natsu's initial attacks against Aldoron prove ineffective due to the dragon's immense size and power. After encountering the God Seed wolves, Natsu learns that direct assaults are futile and devises a new strategy to defeat Aldoron from within. Meanwhile, the reunited guild members battle the God Seeds and their own manifested enemies, determined to protect each other and stop the impending threat.

By the end of the episode, Natsu prepares to execute his plan against the wooden Dragon God.
