The Shepherd of the Great Library

The story takes place in the private Shiomi Academy, where children who have outstanding performance in various aspects gather here, and they carry the glory and hope of the entire city. The library in the academy, known as the "City of Wisdom", is particularly eye-catching. However, in the reading room at the deepest part of the library, the curtain is slowly opening. Keitaro (dubbed by Shimajima Junji) who has a strong thirst for knowledge, Shirasaki Omi (dubbed by Madoka Yonezawa) who is optimistic, cheerful and hard-working, Tamamo Sakuraba (dubbed by Saito Yuki) who is steady, serious and deeply trusted, Senri Mizono (dubbed by Yamamoto Nozomi) who is cold on the outside but hot on the inside, gentle and kind Kana Suzuki (dubbed by Eri Sendai) and carefree Kodachi Nagi (dubbed by Atsumi Tanezaki) (dubbing), six boys and girls who don’t know each other gather here mysteriously, and are about to embark on their magnificent adventure.
