Demon Slayer: Tiger Shadow

On the night he traveled through time, six people in the Kamado family died. Onibutsuji Muzan had just left, Tanjiro hadn't come back yet, and Nezuko was turning into a ghost. There is a line of words engraved in my mind: "Tiger's Breath·Eighteen Types·Heir Xuan" Then the system died. Tomioka Giyu said he "has the taste of a knife". Lintaki asked him "which lineage of ancestors he is from". The first time Butterfly Ninja saw him, he was silent for three seconds. ——Because he knew how she died. But he couldn't say. He can't change the situation. He can only block one more knife in front of every fatal outcome. The tiger's breath, the sword's name is tiger soul. Omniscient, not omnipotent.
