Shinichirou seeks employment to cover his rent, and upon consulting his teacher, is recommended to pursue housekeeping work. However, he ends up working for Sakuya instead, who happens to be the 37th leader of the Shimazu clan - responsible for eliminating undesirable creatures. Inadvertently, Shinichirou frees one of these beasts that Sakuya typically captures, and the two join forces in tackling the situation. Thus, the hilariously adventurous hunt for these creatures ensues!
