After uncovering the truth behind their father's untimely death, life for the four Shimogamo brothers returns to relative peace with each trying to live up to their father's greatness in their own way. For the eldest, Yaichirou, who aims to become the next Trick Magister and leader of the tanuki society, it starts with reinstating the popular shogi tournament. For Yajirou, it is restoring his former shapeshifting abilities, whilst little Yashirou is content with continuing his work at the family’s factory. But for the third son, Yasaburou, it simply means embracing the fool's blood he inherited from his father and living a carefree but interesting life. This, of course, includes hunting for the mysterious and elusive snake-like creature known as a tsuchinoko, and causing ripples of trouble at every turn. However, these ripples threaten to turn into waves with the return of Nidaime, the estranged son of the brothers' tengu teacher, Professor Akadama. Nidaime bears a grudge against not only his father, but his father's apprentice Benten as well. His loyalties suddenly brought into question, Yasaburou must use his tanuki wit to appease all sides without getting caught in the crossfire, before the delicate balance between human, tengu, and tanuki is overthrown and all hell breaks loose.

Aoi was raised as a normal boy on Earth. Little did he know he was the heir apparent to Mito, the Queen-turned-Space-Pirate of an alien race that chooses their sex at puberty! Aoi fell in love with Mutsuki, the police officer who was chasing Mito, and the three of them saved the Universe. The only side effect was that Aoi blossomed into a beautiful young woman. Now a malevolent entity calling herself the true Queen of the Universe appears with enough power to destroy entire planets. Aoi must defend her new throne, but she needs Mutsuki's help. Mutsuki must come to terms with her own feelings for Aoi so they can defend Earth together and become the galaxy's first royal pair of queens.
