is one piece episode 631 filler?

After going "all in" in roulette, the thugs once again lie to the blind man about the results of the game, however this time Luffy reveals the actual result. The blind man ends up engaging in a battle with the thugs, ultimately leaving a massive hole in the floor of the restaurant with the thugs lying defeated within.

Everyone wonders in awe about the blind man's powers. Sanji says he has an ability, and Zoro wonders what ability it is.

As the blind man walks off, he offers to pay for the damages. The cashier thinks she recognizes the man, but before she can say more, the man excuses himself.
