The main strength of the fruit is that Ninamori can produce the ash from various parts of his body and harden it into a dense form that can crush an opponent in its grip, apply blunt force damage, or even be sharpened to cut them. He can spread it from his feet to allow him to cross great distances by creating a bridge or road made entirely of solidified ash.
Being ash, it can be dismantled before it forms by a fierce wind or a surge of water. The hardened ash can theoretically be broken by a strong enough impact, but Ninamori boasts that it is stronger than steel. Other than that, the user is also affected by the standard Devil Fruit weaknesses.
Ninamori uses the ash he produces to form crushing vice grips on his opponents, barrier walls for defense, or sharp cutting blades to dismantle his opponents. He can also create ash roads and bridges to cross great distances.
