The youth Lu Chuan was originally just an ordinary working youth. A strange beast surprise attack, because the armor summoner wantonly fought, made him painfully lose his closest relatives. Seeking help with no door, he accidentally obtained special power, and since then embarked on a path not accepted by the world. The world all views him as a different kind of monster, but the true fault is covered up by the glamorous armor halo. One side is step-by-step pressing pursuit, the other side is limited life and revenge obsession. Lu Chuan holding the bone blade in hand, struggles in the world where black and white are inverted, and with his own way, pursues a piece of ignored justice.
