ROE-396 My mother used to be a villain, Reiko Seo

Reiko Seo plays a mother who was once a female professional wrestler, though her family sees her as kind and refined. The narrator notices odd details around the house, like a bamboo sword, a chain, and clippers, and a folding chair only she sits on, with a red handprint stain on the back. One day he discovers more about her past.
