Human Bullet Tank

A threatening taijutsu trick that converts the user's large frame into a destructive weapon. The user first uses Multi-Size Technique to make themselves into a human-sized ball, then they tuck in their limbs and use chakra to propel themselves into a powerful roll. Its effective use of weight and the force of rotation make for an even greater lethality than appearances would let on, enough to pulverise someone's hand with but a mere touch. It is difficult for the user to turn in this form. This technique has the added effect of plugging up the user's ears.
