Heirodula is a man who lives in the town of Insectaria. He is a very snobby man who considers those "drab" lower than him in wits. In other words, he is your average jerk!
He is only really nice to people he trusts, such as Dulcemer from a town away. This trust issue related attachment is because of the amount of bullying he recieved as a child.
One of Dulcemer's rivals, however, continues the cycle of bullying. If the bullying could even be considered that and not mental manipulation.
