Cindy is very friendly, but mute, and is even known to accompany humans on their journey until it loses interest. Despite this, Cindy is a fairly reserved entity, and it will not interact with humans unless they begin the interaction first. Cindy is docile, only attacking when feeling aggressed. Cindy can change its appearance to disguise itself as one's first love, best friend, or close relative in an attempt to put humans more at ease when interacting with it.
