Senbonzakura

A forbidden technique created by Harumaya to be the ultimate attack and defense. She summons a giant, indestructible pillar of crystal around herself. Upon uttering the command word, 'Shatter', the pillar explodes into an immeasurable amount of crystal blade fragments. While the blades are too small to be seen by the naked eye, they reflect light in such a way as to resemble cherry blossom petals. Harumaya can mentally control the blade fragments, allowing her to surround, envelope, shred, and crush opponents at a distance, break through almost all defenses, while simultaneously protecting herself from any harm, all without giving away her movements. She can use her hands to move the blades, which makes them significantly faster. The blades can be manipulated into various forms and constructs at her mental command, giving her a wide arsenal of attacks with this ability.

In order to protect herself from her own attack, she possesses a Hurtless Area (無傷圏, mushōken; lit. "Woundless Zone") where the blades do not cut anything within 3ft of her form unless she herself allows the blades to enter the area. This zone moves as she moves, thus enabling her still to be mobile during this technique.

However, she is unable to use any other technique while using this ability, only its derivatives.
