A young man is transported to another world where he helps to rebuild its flagging economy.

Julius, the son of Gaius, attempts to reclaim his former territory of Van from Souma, backed by the authority of the Gran Chaos Empire; the power to negotiate is given to Jeanne Euphoria, the younger sister of Empress Maria Euphoria.
