Using the latest technology, the Millefiore Famiglia was successful in embedding Boxes in the human body. One theory says that there was no choice but to embed the Box inside a body, as the Box's power was so extreme that its performance is unstable by itself. At any rate, it is a Box Weapon that conceals an amazing fighting power.
In the present, Zakuro has the External version of the Asura Box.
Through this Asura Box, Zakuro becomes a hybrid between human and Tyrannosaurus with Storm Flames emitting from his shoulders. His size and physical abilities are increased, and his skin becomes far more resistant, to the point of being called impenetrable. He also has regenerative abilities strong enough to recover lost limbs, although it has been noted he cannot do it as fast as Deisy.
