Random bond Hamiltonians of the $\pi$ flux state on the square lattice areinvestigated. It has a special symmetry and all states are paired except theones with zero energy. Because of this, there are always zero-modes. The statesnear $E=0$ are described by massless Dirac fermions. For the zero-mode, we canconstruct a random lattice fermion without a doubling and quite large systems (up to $801 \times 801$) are treated numerically. We clearly demonstrate thatthe zero-mode is given by a critical wave function. Its multifractal behavioris also compared with the effective field theory.Comment: 4 pages, 2 postscript figure
