Name: Nulo Vacío / Null Void
Looks: A torrential burst of black and white, pouring forward like a wildfire.
Effect: Put simply, Nulo Vacío is almost like any normal Gran Rey but with an added effect that makes it all the more useful. Being formed of an unstable concentration of reiatsu and energies, it has certain qualities a normal cero lacks. For one, it can be released much like a normal cero, after a quick charge, without the need of using your own blood as a catalyst. If the cero clashes with a technique that is weaker than it is, nothing out of the ordinary will happen. But this is where it gets interesting. After the large concentration comes against any other attack with superior power, the unstable concentration will blow out. Opening a small void around the spot where the two attacks met. Essentially nullifying both of them. The cero serves as both, an attack and a surprising defense. This cero is based on a residual system where the user gather small amounts of reiatsu over a large time and dedicate the gathered power for this one attack. That is why the cero doesn't exhaust him that much, but has a large cooldown in exchange.

Training: 3.5k or something. Not too sure about the current cero training rules. If the old ones apply, 5k.
