   Summary

   Momo Nishimiya has always known something was off about her twin brother. Many, whisper of how he was stillborn for a few moments attributing to his strangness.

   To worsen things, her brother Kuroki Nishimiya seals away a quarter of his own power with a Binding Vow, one that rewards him every time he defeats someone stronger than himself. The closer to death the foes is, the better the reward.

    

   To the Nishimiya clan, he's a promising son with a strange few quirks. But to Momo, it's a wrongness she can feel tightening around him. A wrongness and addiction to only worsened, by Jujutsu society's desire to praise even the wicked.
