We construct a model of moonshine phenomenon based on the use of N = 2 superconformal algebra. We consider an extremal Jacobi form of weight 0 and index 2, and expand it in terms of N = 2 massless and massive representations. We find the multiplicities of massive representations are decomposed into a sum of dimensions of irreducible representations of the group L-2 (11).
