Totoyamu is one of the Forest Men. He is mentioned in Syrus' folktales as incarnation of the divine spirit Mamon.
The player must find him to retrieve the Calabas Herb. After some events, the player must find him again and give him the Champion's Belt to discover the way to the Divine Tree, since he is the guardian of the Tree.
In the Netherworld, he is the final elemental boss of the Spider Forest, and hates humans for being selfish beasts.
