Wavelength compression (波長圧縮, Hachō Asshuku) is a special ability used by certain demon weapons, notably gun-type demon weapons.[1]


Wavelength compression allows a demon weapon to compress a wavelength (particularly a meister's own) and create high density attacks. With meisters using demon weapons with this ability, they're capable of shooting potentially unlimited bullets so long as their souls are healthy and intact.[2]
