Black Ice (黒氷 - Kurohyō) is one Yumi's reoccurring Ninja Arts in the Senran Kagura series.
Yumi spawns a series of miniature icicles, all which come together to form a frigid lance before launching to pierce her foes from afar. This attack can freeze her enemies.
Firing it from an open and even place is virtually a must, as it will dissipate should it come into contact with a wall or any other obstacle.
Yumi spins her fans in front of her causing her enemies to be sucked in before pushing the fans toward them and firing a frigid ice lance out of the center. This attack can freeze her enemies.
- Black Ice is a Secret Ninja Art originally used by Kurokage. However, during Yumi's training he passed it on and taught it to her.
