"Violent fighting to begin again!"
From the book's opening:
"Thrash is a book-and-dice RPG that deals with anime and fighting game style martial arts. This main rulebook presents only general rules, info on real-world martial arts, and some general fighting game info, though additional sourcebooks will deal with an assortment of popular fighting game worlds.
The Thrash system is heavily based on the now out-of-print Street Fighter Storytelling Game from White Wolf, as well as Mekton Z, and, to a lesser extent, Ninjas and Superspies. The martial arts and the whole system are designed to simulate both fighting games and anime and manga based on them, the result being a highly cinematic game with lots of nifty special moves, energy blasts galore, and so forth."
