Z/X: Ignition

Despite having only 12 episodes, Z/X: Ignition earned a name for itself as a trading card anime. Portals to parallel universes begin to appear, and weird species begin to infiltrate the human world. Five invading forces emerge from these five Black Points to battle each other and destroy the other timelines.

While the ending of Z/X: Ignition is obvious, the original tale blends supernatural and action aspects to create a unique story. Furthermore, the action is fast-paced and enjoyable, and the fights are very wonderfully depicted.

12 episodes
