Blazblue: Central Fiction, much like other anime fighters, has a lot of depth and mechanics that lend themselves to creating unique and difficult-to-perform combos. Even some bread-and-butter combos are entirely situational, and can thus be difficult to pull off every time.
With these combos, we see the cream of the crop in impracticality! With liberal usage of rapid cancels, we see multiple characters — including Susano’o, Valkenhayn, Hazama, and Terumi – -pushing the Blazblue combo system to its absolute limits.
