Bakuen Campus Guardress - Season 1 Episode 3 Ache Ache Pant Pant - The Stressful Final Battle!

Sitting alone in her room, Hazumi sulks over her inability to protect Takumi and losing her sword. Her mother walks in and chastises her on working on her boobs and butt, but not on her brains. She explains that she hit Hazumi as a form of shock treatment. This makes Hazumi suddenly realize: it may have been shock that made her sword disappear. She makes another try to summon it, and only ends up with a mop. Despite this, her mother manages to cheer her up somewhat.
