This Paramecia gives its eater, the Donquixote officer Diamante, the power to make himself or any object he touches go flat and supple, billowing like fabric. The effect earns him the nickname Flag Human, since hardened metal can be made to wave in the breeze at his word. The fruit's name comes from hirahira, the Japanese onomatopoeia for flapping or fluttering.

Affected material gains the foldable, flexible qualities of cloth while keeping every other property intact, so flattened metal still resists impact and a blade keeps its edge. The user can crease and refold flattened items into new shapes at will. Diamante uses this both ways: a steel cape lies limp like a banner until an attack comes, then breaks the incoming sword, and flattening his own body into a flag form lets him drift safely to the ground when he falls. It remains unclear whether the ability works on other living things besides the user. Aside from the ordinary Devil Fruit weaknesses, the fruit shows no special drawback.

Diamante is the only user, and he turns the power into an unpredictable arsenal. His rapier can be stretched into a whip-like urumi, reshaped into a mace, or hidden as a flattened medal. Named techniques include Lock and Hira Release, which undo the effect to restore an object, often hardening it in the process; Corrida Glaive, folding his sword into a bull's-head mace; Vipera Glaive, a flattened blade that snakes toward its target; Army Bandera, rippling the ground to unbalance nearby foes; and his ultimate Death Enjambre, where folded confetti cannons fire flattened iron balls that rain down like deadly stardust over an entire battlefield.
