Bloodcurdle

Bloodcurdle (凝血) is a Quirk used by Chizome Akaguro.

Description
This Quirk allows Stain to paralyze an opponent by ingesting samples of their blood.

As long as Stain has access to his foes' blood, he becomes able to immobilize them for a limited period of time, turning them into easy targets. Stain can facilitate his access for blood by using sharp, long-ranged weaponry like swords, which tend to become stained with blood after cutting through tissue.

The amount of time a victim remains paralyzed depends on their blood type in relation to Stain's own. In Stain's case, blood type B represents the longest amount of time, then decreasing to AB, A and finally O for the shortest amount of time. Regardless, the maximum amount of time anyone can stay paralyzed for is 8 minutes.
