Samara

Samara is a very timid ghost. She does not like to scare humans, like her friends, and so is excluded from jokes, activities, etc. This act of the other ghosts left her quiet and depressed, being one of the least to leave home in her family.

Samara is very fond of cats, because they soothe her. Having a kitten around is the same as making her very happy. Consequently, she hates dogs, especially dogs that startle her "little friends" (she calls the cats of little friends)

Samara loves music, but prefers the sounds of nature. She is able to spend hours under a tree, only listening to the wind, or the leaves falling.

She met her girlfriend, Kamimi, when Kami ventured into the mansion where Samara lives. The ghost saw the human, and even in fear, she warned the girl to leave. The girl left, but came back every day to see Samara. Something about her enchanted Kamimi. 

The two became a kind of "colorful friendship." Even though they are dating, they continue to act as friends.
