Thorigoron Drimmurr.

An anthropomorphic goat who protects people who have fallen into a dungeon with monsters from the monsters themselves because his ex-wife, Asgiebel, with whom he is divorced and who is also the current queen of monsters, takes human souls to save her people from this imprisonment by humans, despite the fact that she asks for the consent of a human girl or boy, since all this time they have only had human youth, that is, teenagers, that is, no children or adults have ever come across them.

Since then, Torigoron protects any fallen person precisely because he or she cannot be harmed and does not sacrifice themselves. In order to protect them, he asks them to stay in his house, since the castle belongs to the queen.

He has a biological daughter, Asriel, who has been severely injured by humans multiple times. He has an adopted son, a human boy named Chara, who hates humans and escaped them into the dungeon. Later, the fallen human arrives, a boy named Frisk, and Torigoron regards him as his son.
