Hard-Light Technique

Using this technique, Ace is able to convert his entire body into Hard-light. This light is hard enough to withstand bone-breaking hits from oncoming projectiles. Ace uses this technique to achieve Lightspeed movement for his next technique, Instant Taijutsu: Lightspeed Punch.

If Ace didn't use this technique and attempted to use Instant Taijutsu, it would't initiate, as it take potentially an infinite amount of chakra to do so.
