Gakuto no Vector  

Student Vector, 学徒のベクトル

A student discovers that Minazu Aruto enjoys reading novels and short stories, so they suggest a school-sponsored club called Philosophia. Although the name piques Aruto's interest, he doesn't fully understand what the club entails. Nevertheless, he decides to investigate further. He visits the campus library, where he meets and is introduced to the three members of the group: Tomoe, Takaho, and Kaede. Despite not receiving a clear explanation of the Philosophia club's purpose, Aruto joins, assuming it is a literature-focused organization.
