Hmmm... maybe I should put it in context if that will make a difference.
 The full phrase is...

"Kora Geki, Bora Gyo, Supi-Do To, Subete No Barasosu Gatoreta Kyarakuta-."

...which I've translated so far to mean something like...

"Attack, Honorable Defend, Fast Person, Balance of All <something> Character."

It's a line from the Super Battle manual on page 20 (Ranma male).
Any ideas?
