Can't believe after so many years following this, I get to mark it as complete. Sad to see this go but I did like the ending & Mikage deserves it. Thanks for completing this series & look forward to both the author's & artist's next work.
@bombypupe I guess they intentionally lose it to grow old alongside their partner and/or to hide their identity as a witch, but Mikage chose not to lose her powers as she needs them to keep her love alive, and he learned of her identity and would rather reincarnate multiple times to be with her instead of having her die alongside her.
