Background[edit]

Ui belongs to Trinity General Academy and is the chairman of the library committee. She loves books and is also a bit of a misanthrope, although it is unclear which of the two comes first. She is particularly fond of old books, and spends her days in seclusion, deciphering and managing old tomes at a place called the "Antiquarian Bookstore". Her intellectual curiosity and her knowledge of antique books are first-rate, and she is even called the "Sorceress of the Antiquarian Bookstore" by those around her.

トリニティ総合学園所属、図書委員会の委員長。
こよなく本を愛する少女であり、鶏が先か卵が先かは不明なものの、同時に中々の人嫌いでもある。本の中でも特に古書を好んでおり、彼女自身も日々「古書館」と呼ばれる場所で古書の解読や管理を行いつつ、引きこもるようにして日々を過ごしている。その知的好奇心や、古書に関する知識および技術は一級品であり、周囲から二つ名として「古書館の魔術師」と呼ばれるほど。

How to Obtain[edit]
