Second season of Muhyo to Rouji no Mahouritsu Soudan Jimusho.

Mushi: the most basic forms of life in the world. They exist without any goals or purposes aside from simply being. They are beyond the shackles of the words good and evil. Mushi can exist in countless forms and are capable of mimicking things from the natural world such as plants, diseases, and even phenomena like rainbows. This is, however, just a vague definition of these entities that inhabit the vibrant world of Mushishi, as to even call them a form of life would be an oversimplification. Detailed information on Mushi is scarce because the majority of humans are unaware of their existence. So what are Mushi and why do they exist? This is the question that a Mushishi, Ginko, ponders constantly. Mushishi are those who research Mushi in hopes of understanding their place in the world's hierarchy of life. Ginko chases rumors of occurrences that could be tied to Mushi, all for the sake of finding an answer. It could, after all, lead to the meaning of life itself.

Silent, apathetic, yet mischievous, 14-year-old Rokujou Miharu is the bearer of the hijutsu Shinrabanshou, a powerful technique many ninja clans desire so they can become the ruler of Nabari. His classmate Kouichi Aizawa and English teacher Thobari Durandal Kumohira are both secretly Banten clan ninjas who have pledged themselves to protect Miharu from his many attackers. Keeping apathetic, Miharu attempts to reject their invitation to join their ninja club. However, after numerous attacks, he finds no choice but to join their group as a means for his survival. Slowly, Miharu gets ever closer to becoming the ruler of Nabari.

This is the prequel of My-Otome, which predates the events before the My-Otome Series. In this series, it focuses upon the origins of Lena Sayers, the mother of Arika Yumemiya and former bearer of Lofty Crimson Jade / Blue Sky Sapphire GEM, and Sifr Fran, the biological mother of Nina Wáng and the former queen of Windbloom Kingdom, as well as the origins of Schwartz, Aswad, and the Garderobe Academy and its Five Columns. The kidnapping of Sifr and the powerful revelation of Lena's GEM will soon fatefully determine the outcome of the future for themselves and the others around them. (Source: ANN)
