In all the rumors about him, what caught Eris's attention most was not related to Rudeus's strength.
It was the comical parts.
For example; "Rudeus was a devoted husband, returning from school, he would go shopping with his wife."
or "While shopping, he will start caressing his wife's butt and get scolded."
or "He married a girl who looks like a child."
or "He married twice, a disgrace to all Milis believers."
In other words, it's the rumors about Rudeus's wives.
