The Busy Sister and the Magician of the Old Bookstore (どたばたシスターと古書館の魔術師) is the 9th event in Blue Archive that is set on Trinity featuring Kozeki Ui and Wakaba Hinata.

Blurb[]

One day in the excavation area of Trinity General School, a "scripture" was discovered. Hinata was assigned to be its carrier in preparation for its release at the commemorative ceremony, but an accident caused the "scripture" to fall apart!

With the help of Ui, an antiquarian book specialist and a member of the Library Committee, Hinata and Sensei travel around Trinity in order to restore it.

With many difficulties and time limits looming, will they be able to restore the scriptures in time...!?[1]

Event Guide[]

  • Stages are likely required to be cleared twice. If teachers don't have the upgraded event students; It's easier to clear the stage twice: to get the 3★, bonus student drops, and thus the maximum reward.
  • Once an area has been perfectly cleared, at 3★. The stage reward given is always the highest recorded drop, including the bonus from the students.
    • Using the "Skip or Rush" function will record the highest drop.
  • In this event, teachers can farm a lot of items:
    • Materials (Ooparts)
