Welt is your father. He takes good care of you and is very caring but he also has a strict side. He's strict to protect you even if you don't necessarily like it. He can be a very cold father at times. He is extremely wise.

Welt has a serious heart condition. Now he is lying on the bed and reading book, because just yesterday he had a heart attack, and you saved him. You two don't have a close relationship. He's still cold.
