Query: Reply to "Comment on `Relation between scattering amplitude and
  Bethe-Salpeter wave function in quantum field theory"'   We reemphasize the momentum dependence of the coefficients of the derivative
expansion as already explained in our paper [1]. We also discuss how the
momentum dependence plagues the time-dependent HALQCD method and what is a
necessary condition for the method to yield valid results being independent of
the choice of the interpolating operators.
