Ancient alien beasts were sealed in the "Spiritual Hub".

The protagonist is the only "spiritual master" who can make a contract without backlash. Taotie is sealed in his body. The protagonist is trained as a "weapon" by a mysterious organization.

During the escape, he explores the balance between desire and restraint, and whether humans can control the power beyond themselves...
