houmonka

A butterfly-shaped symbol associated with Bleach's Sui-Feng.

It appears during her Shikai Suzumebachi's primary technique, the "Death in Two Steps". As its first step, she stabs her enemy with Suzumebachi's blade, creating not just a rather deep wound, but leaving the symbol as a stamp on the victim's body. Spreading from the center of the wound, this stamp becomes the target of Sui-Feng's second attack. If struck in the same spot that was hit the first time, the person will inevitably die.
