As the giant lost its balance and started descending, Layton who was shrouded in the huge shadow caused by the giant's quick descent lightly tapped the ground, in the blink of an eye he had left the ground reappearing in mid-air his body right above the giant's head clenching his fist he activated his armed haki once more and used his legs to kick the air to provide thrust moving him downwards towards the giant's forehead, thrusting his fist to the grey skin he mobilized all the muscles in his arm, they twitched following the peculiar rhythm and even Layton's heart and biomagnetic field broke free from their natural operations and followed the rhythm.

 The fist made a loud boom as it tore through the air and hit the giants head squarely.

 Although the fist was the size of a mosquito bite to a normal person but the immense power Layton's punch generated directly penetrated the giant's coarse stone-like skin and burst its head-turning into fragments.
