Yuusha ni Zenbu Ubawareta Ore wa Yuusha no Hahaoya to Party wo Kumimashita!

When the Hero’s mother was cast aside by his father and replaced by a younger woman because she was deemed no longer desirable, the Hero didn’t seem to care much about this situation as he wasn’t particularly close to his mother to begin with. Seeking revenge against his former party, our main character decides to form a new party with the mothers of his previous party members. In this magical world, it appears that people are indifferent to the value or worth of women over the age of 18, leading the main character to believe that forming a party with these women would be a satisfying act of retribution.
