Riki-Oh: The Story of Ricky is my favorite b-movie. Martial arts, horror, prison, low-budget effects- yes, please!

Strength .7-1, optional master training tag is scene from r1k1-0H and it seems to work better toward the end of your prompt if you use it.

Other things it likes- general prison related terms, industrial meat grinder, martial arts, punching someone's head off, etc.

Drop strength a little if you don't want the subject Asian. It may be unavoidable at times though. Master trigger increases Asian-ness a little.
