The Truth of Ten Years Ago - S1.E20

Anji tells him about the past: As everyone is fighting the Zakums, Anji tells them to surrender, since everyone knows that Zakteman is stronger than all. They also find out that all the weapons are gone. As everyone still continues to fight, seeing Zakeman approaching, Grande goes towards him. Anji was the one who stole the weapons and brought Zakteman to the World Tree and betrayed his friends, trusting Zakteman to not harm his friends. As Zakteman tries to hurt him, Grande arrives to save him, and tells him that it is important to trust, but also to know whom to trust. As Grande blocks Zakteman's attack, his sword, which is made from the World tree, shines brilliantly, just as the World Tree explodes to protect itself. When Anji regains consciousness, the World Tree is gone, and Grande is gone. He finds Grande's sword and returns it hoping that a great warrior would appear some day. Coming to the present, they see the Golem destroying the city. Anji is confused, since the Golem used to be the protector of the forest. Since the Golem is not affected by any of their attacks, Al suggests that they take away the bad memories from the Golem and return it to be the protector of the forest. They also receive help from Gill, who was listening to Anji's story and they are able to save the Golem.
