Nekomata

Encyclopedia Entry:
A kind a werecat living in the Zipangu Region. Filled with a high level of magical power, her tail has split into two. Her magical power has allowed her to take the form of a mundane cat. In Zipangu, where monsters and humans live in peace, she usually takes her true form, but either form can be seen there.

She often spies on men she’s taken a liking to, while disguised as a cat. She comes up close to him and charms him using her magic. Men who are kind and generous will surely be made into targets. She follows the usual “Run when he comes close, come closer when he runs” thought process. In addition, she may approach the man on her own. If he backs away, she’ll give up hope immediately, but if the two are comfortable with each other, she’ll stay close to him. She will also rub up to him to coat him with her scent, to keep other monsters away from her prey.

Yet, she’s still a monster, so her true nature can’t be hidden for long while so close to a male. Eventually, she will assault her prey. In that case, the longer she waits (usually about a month) the more violent she becomes. Her desire for the man will be unleashed as her warm body becomes joined with his, and she takes some of his spirit energy.

It is believed that “a cat that lives for many years gains magic and becomes a nekomata.”   This is wrong. If a cat that absorbs demonic energy they become a nekomata. In some cases, the cat may have been a nekomata from the very start. Encyclopedia Pages
