Testing out a new fighting style against beings that can actually kill her if she's not careful is not only dangerous but incredibly stupid. Yet, Mira did just that. She used the entire hour against the duo to hone her new fighting style, which she found both difficult and extremely rewarding.
It was almost like she was trying to create a brand new Martial Art in the midst of a life-or-death battle!
The basics of this Martial Art is to have an incredibly strong body. High regenerative powers would also help, as the moves she performs can damage the body due to the amount of force she's generating.
For her to perform several contradictory actions at the same time, Mira essentially needs to flood certain parts of her body with Qi, so she can explode with power to counteract the force generated from her contradictory actions.
