The Dark Chidori is a powerful ability used by some especially powerful Tenebrosi. This ability is among the most powerful that a pure Tenebrosi can learn without the need to access a Fusion State. However, because of its power and the way in which it is generated and maintained, the Dark Chidori requires exceptional patience and concentration to master, and only a select few citizens of Tenebros have those. It also requires large amounts of raw umbrakinetic power to use and as such, it should not be used for extended periods of time.
