A Good Librarian Like a Good Shepherd, 大図書館の羊飼い

The legend of Shiomi Academy's Shepherd says that this mythical figure appears before diligent students to grant them one wish. Kyoutarou Kakei, a second-year student at the school and president of its Library Club, receives an email from the Shepherd about an upcoming event that will significantly impact his life. Concerned by the message, he rushes over to a nearby train station where he saves Tsugumi Shirasaki from being hit by a derailing train. Grateful for Kyoutarou's bravery, Tsugumi joins the Library Club and invites him to participate in her "Shiomi Happy Project." Along with other new members of the club, they work together to improve the academy and uncover the secret identity of the Shepherd.
