(prosthetic leg au)

atsushi was on mission with akutagawa as always and of course akutagawa cut off atsushi legs but this time atsushi didn't have any energy to grow it back so he lost the legs and it only heal the around the knee

atsushi was took to a hospital by akutagawa surprisingly and the doctor said atsushi knee was heal so he could be fitted for a prostate leg but he can't grow back the legs now.

atsushi just call one of the agency member.
