I was actually losing against a GP as Jax for a while, especially early on. But once I had built armor and some more offense I wasn't bothered by his Parrleys.
It really depends on the Jax and the GP in question... maybe he wasn't prepared for me to handle him by building armor. --- Shikou Mibuya: I'll save you little boy! Let's go to a world only with men! A dazzling world! Fumiko: He doesn't like sausages. Too bad.(Castle of Shikigami 3)
