Bunshi Kasoku

 is the result of further mastery of Hotaru's own ability to manipulate molecules with his chakra. Bunshi Kasoku, allows him to speed up molecules to the extent that they either catch fire or melt. He can accelerate molecules, be it his own or another. He can speed an object's molecules to the point of melting or combustion. Using on himself grants him the ability to travel at extraordinary physical speed. He can move far faster than the average member of the his race, above supersonic speed or even faster, possibly reaching or even exceeding mach 2 speed. This jutsu is not without any ill effects however, as it can strain the body, but some users may be resistant or even immune to the effects of high speed travel including friction and inertia.
