Nerval

A brain-colony. Though unlike the mostly benign yet troublesome Leopard, Nerval is a malignant entity who seeks the enslavement of humanity. He is aided by a loyal movement of people known as the Nervalists. He takes the form of a yellow hair male and Takane served as his guard before she regained consciousness. He however fears Leopard as Leopard is a very unpredictable character. Nerval's brain is already completed and he first attacked the lunar base, by freezing the whole moon and the fleet. Nerval wants to understand the humans and therefore starts to do so by cooking. However, after Kagura thought him that seasonings will make the Naporitan tastier, he used them on Manmaru-yaki too.

When talking with Tsutsuji, he was compared to Pinocchio by her as he is similar to Pinocchio who wishes to be human. He later approached Leopard and was defeated after Leopard used his "Soul Shout" energy attack.
