The second season of The Eminence in Shadow has been a turbulent one, with spectacular fights occurring one after another. Following Aurora, The Tower Monarchs, and Blood Queen Elisabeth, viewers are introduced to a new villain whose scheme could devastate Shadow Garden's company, the Mitsugoshi Corporation. In order to prevent this from occurring, the always ridiculous-but-likable Shadow takes on a new identity as John Smith.
