I know he moves forward but he still hits too far away from his leg. Like on Buppa's last match against Dora (http://zoome.jp/gamechariot/diary/173 3rd match).
I can only think of two possibilites:
1 - the "laser" has a hitbox on its own.
2 - I don't really grasp the correct size of these hitboxes and I'm probably misunderstaning the distance shown on the hitbox video with the in-game distance.
