Hijin Kessō

was one of Inuyasha's attacks. By drenching his claws in his own blood, Inuyasha could use his Hijin Kessō to charge the blood with yōki and sling it like a barrage of crescent-shaped blades. While he typically used blood from an already open wound, Inuyasha could draw the necessary blood to use the attack by digging his nails into his palms. He would often use this tactic as a surprise counterattack after being wounded, when his opponents would assume he was weakened by his wounds and lower their guard.

Trivia

 * In the video game Secret of the Divine Jewel, using this attack will lower Inuyasha's.
