Kyousuke Tamamo

Tamamo (玉藻), also known as Kyōsuke Tamamo (Tamamo Kyōsuke玉藻京介) in his human form, is the most important of the yōko in the manga series, a powerful being who is both Nūbē's ally and ultimate rival. First arriving at Doumori Elementary as a bishonenous male teacher who wins the hearts and minds of his students and fellow staff, his true intent was to seize the skull of Nūbē's student Hiroshi Tateno which is his 'perfect skull' for transforming into a human. When Nūbē was forced to come to Hiroshi's rescue, the two got into an intense battle upon which the true form of the golden fox-creature was revealed and nearly defeated Nūbē. Due to Hiroshi's courage, however, Tamamo was defeated, though not for good. He returned soon after, intrigued by Nūbē and how his powers was amplified when fighting for his students. He learns that it is the power of the human heart, and not understanding it, tries to know more by creating situations that force Nūbē to fight or via simple observation. Tamamo also abandoned his teacher's disguise to work as a doctor in Doumori Hospital, where his 400 years of knowledge accumulated to cause misery went into healing others, which he thought would be a good way to learn more about humanity. Having existed and trained his spiritual powers for centuries, Tamamo has become adept in many spiritual powers and abilities that he holds even without perfecting his "transformation jutsu". He is a master of "illusion jutsu", able to manipulate anyone to see whatever he portrays as long as there is motion. (even to the extent of creating clones of himself off the display of video game screens) Offensively, he uses a "yōko foxfire jutsu", allowing him to create and control a powerful fire-based attack which he can increase and power and intensity to burn his opponents. He can also handle certain other spiritual abilities like Nube's such as assisting in controlling spiritual energy and even the "youshin jutsu". When not using spiritual power, his main weapon is a paw-like neck catcher, which primary function is the extraction of suitable skulls for his "transformation jutsu", but can also be broken apart to surround himself and an opponent within a barrier for more powerful attacks. In the manga, it was revealed that the skull he was currently using in the course of the series came from a dead mountain climber, who was a well-to-do college student.
