When does blazican learn slash?

It seems you're asking about the character Blazican and his learning of the slash. However, there's no information about a character named Blazican in any known fictional universe.

Could you please provide more context? Perhaps you're thinking of a character with a similar name or a different spelling?

To help me understand your request better, please tell me:

* Where have you encountered the name Blazican? Is it from a book, game, movie, or something else?

* What kind of slash are you referring to? Is it a sword-fighting technique, a programming language, or something else?

With more information, I can hopefully give you a more helpful answer.
