Higeki no Genkyou to Naru Saikyou Gedou Last Boss Joou wa Tami no Tame ni Tsukushimasu. The Savior's Pride

At eight years old, Pride recalls her past life and recognizes this world as one from an otome game, with herself as the final boss queen. Determined to avoid a grim future, she works to prevent the fates of those marked for capture. As months pass, her sixteenth birthday nears. A public announcement of her engagement is planned for the celebration, but Pride, preoccupied with reforming the school system, has entirely forgotten the event.
