Nezu (根ね津づ, Nedzu?) | Nezu is an eccentric, polite, and persistent educator. He is quite self-aware of his odd appearance and introduces himself by pointing it out. He can be very long-winded at times when explaining or educating. His dedication to educating goes as far as assessing villains, especially young ones, and wondering if they could be put on the right path if they were taught, although he admits the naivety of the idea.
