Hayate No Gotoku - Like a Hurricane

This near-death skill was used by Hayate when he gathered all his strength and power to unleash a kamikaze-type attack with flashing speed as the name reads " Like A Hurricane" to save his lady Nagi from an evil giant robot. With its almighty destructive power it renders the users body helpless after use as Hayate felt like every bone in his body broke.

Hayate first used it in Hayate No Gotoku!! Episode 3: And The Legend Does Not Start

However, it appears to that Hayate has mastered it somewhat, as he appears to be fine after he uses it to defeat Yukiji in chapter 70. This suggests that his body can now withstand the strain of the technique, or that he can adjust the intensity of the technique, or both.
