This is the most common question regarding the light novel ending. Yes, she does. Just as in the anime, the conclusion of Volume 3 sees Mirai reappearing before Akihito after the barrier is mended.
However, the mechanics of her return are less about flashy animation sequences and more about the lingering connection between her cursed blood and the youmu core. The novel emphasizes that her return is a miracle born from the specific circumstances of her sacrifice and Akihito’s refusal to let her go.
