By carrying out Monte Carlo simulations,we study step bunching during solution growth. For simplicity, we consider a square lattice, which represents a diffusion field in a solution, and express the diffusion of atoms as the hopping of atoms on the lattice sites. In our model, we neglect the fluctuation along steps. An array of steps is expressed as dots on a one-dimensional vicinal face. Step bunching occurs in the case of step-down flow. In previous study (M. Sato: J. Phys. Soc. Jpn. {\bf 79} (2010) 064606), we studied step bunching with a slow flow and showed that the width of the fluctuation of step distance increases as $t^\alpha$ with $\alpha =1/3$ in the initial stage. In this paper, we carry out simulations with a faster flow. With a faster flow, the width of the fluctuation of step distance first increases as $t^\alpha$ with $\alpha=1/2$,which is larger than the exponent with a slow flow, and then an interval during which the width increases as $t^{1/3}$ appears.
