Library War - 1x10 - Explosion of Backing Home- Followmy.tv

The library task force is sent out to train a peace loving library in Ibaraki Prefecture where there will be a prefectural art exhibition. There, being the first woman in the task force, Kasahara is constantly bullied by others during the mission. They even go as far as calling up Kasahara's mother and informing her of Kasahara's activities. Kasahara and her mother eventually reach an understanding and it is revealed that the reason why Kasahara's mother is so protective is because of an accident when Kasahara fell as a child and hit her head. Kasahara strikes back at the members of the Affairs Department and inspires Defense members to stand up to them as well.
