Shizuko

Zect's mother, Zector's ex-wife and Ceres' wife, and one of the main heroines. She was sold as a slave by her ex-husband, later being bought by Ceres and join him in a new adventurer party. In this isekai world people only live up to around their mid forties, so she is considered an old lady nobody wants to bang anymore. Things develop rather quickly and Shizuko ended up marrying Ceres. He gives her the attention she was denied by Zector. The given attention extends from cooking and protecting her to absolutely pounding her like a madman in bed.
