  We reconstruct a complete type II superstring field theory with L-infinity
structure in a symmetric way concerning the left- and right-moving sectors.
Based on the new construction, we show again that the tree-level S-matrix
agrees with that obtained using the first-quantization method. Not only is this
a simple and elegant reconstruction, but it also enables the action to be
mapped to that in the WZW-like superstring field theory, which has not yet been
constructed and fills the only gap in the WZW-like formulation.
