This Kekkei Genkai causes the person to have 2 color eyes. The Purple and Red eye are the Deadliest because the the red eye sends a raging inferno blast at a target that combines Fire and Wind Style Chakra Natures. If it touches it touches the person it spreads son their body instantly. The purple eye can paralyze a person if their chakra is not greater than the person with the purple eye. It also can make replicas of up to 1000 of their swords. If their right eye is trained enough in more than one chakra nature, their eye color can change.
