Zu has a certain regressive disorder where her mind retains that of a young, immature child. As with many children, their minds can be influenced easily, and, combining that with puberty, makes Zu certainly susceptible to... Particular emotions.

-"A name is a means of identification. A rock is a 'rock.' A chair is a 'chair.' It is completely possible to go nameless, to be identified only by distinctive traits one carries."-

She's simple-minded like that. :3

I liked this but it was kinda weird.
Zu gets raped to the point of having a break down but as soon as the first cat guy she sees becomes nice to her she gives him the best fuck of his life?
On the bright side Zu won't get bullied again and is now happy, and sixten finally gets a break and finds a really good girl.
