ねこさん

While Alice is trying to find his way through a lush forest, he hears a strange voice calling him. To his surprise, he see it is the floating head of a cat girl. 
Neko-san (as she calls herself), loves to bother Alice. With a fun and energetic personality, Neko-san never takes things seriously (unless it includes an evening alone with Alice), and although she is not as bizarre as her counterpart in Carroll's novel, she always has a smile on her face. 
With her power to disappear, Neko-san scares Alice whenever she can, and sometimes her jokes seem to have no limit. She never misses an opportunity to suggest that she and Alice should do "little things" together.
