Bijo Bijo no Mi

The Bijo Bijo no Mi is a Paramecia-type Devil Fruit that allows the user to convert sound into light to do various things.

Strengths and Weaknesses
This Devil Fruit has the ability to transduce sonic vibrations, which reach the user's body into various types of light. This ability seems to operate over a great range of frequencies, including the audible spectrum (35 to 16,500 cycles per second), and a great variation of sound pressure levels regardless of the complexity, dissonance, or randomness of the sound. For example, a cart crash and a symphonic passage of equal duration will both produce usable music incoming acoustic vibrations.

Not only this, but the user possesses a body-wide energy field that controls the energy levels of the outer electron shells of their body in such a way as to cause the cascaded release of photons. In effect, this field is lasing, with the apparent efficiency of a laser (99.9%). The released energy is far greater than the incoming kinetic energy and therefore must involve an outside energy source, the nature of which is unknown. Left undirected, the light will radiate from their body in all directions, producing regular flashes of white light (white light is a mixture of all portions of the visible spectrum).

By conscious control over the light they produce, the user can control its direction, frequency (color), amplitude (intensity), and duration. The user can produce numerous effects with the light they converts from sonic vibrations. They can create very simple patterns out of rays of light like circles, squares, triangles, and stars. Anne can create a pulse of light on the order of several thousand watts seconds of power, which temporarily blinds people with its brilliance.

Dalzeel and Anne have learned to manifest their light as lasers by concentrating, they can generate a coherent beam of light, approximating a laser beam. The field thus operates in a similar fashion as the process that creates a laser (Light Amplification by Stimulated Emission of Radiation) and apparently has the same efficiency as a laser (99.9 percent). The released energy is far greater than the incoming kinetic energy and therefore must involve another, unknown energy source as well.

The user cannot use any sound produced by their own body. Despite the limits of her sound conversion ability being unknown, both Dalzeel and Anne demonstrated they were capable of absorbing the sonic waves of Yebisu's "Oceanic Beat", a technique known for its detrimental power. Not only this, but the user must consciously or subconsciously will the light to leave their body. Otherwise, light would “leak” from them at all times, even when they are asleep or unconscious. Aside from this, the standard weaknesses apply.
