What is the anime burst angle about?

There is no anime called "Burst Angle." It's possible you might be thinking of a different anime, or perhaps a fan-made concept.

To help me understand what you're looking for, could you provide more information?

For example:

* Do you remember any other details about the anime? (Characters, plot points, setting, etc.)

* Is there any specific animation style or genre you remember? (Mecha, romance, fantasy, etc.)

* Do you remember any keywords or phrases from the title?

With more information, I might be able to help you find the anime you're thinking of!
