Here is Karuto she has white hair and white eyes as she mostly wears her  black robe,

She is a leader of a cult of girls that praise the dark and do rituals too and sometime sacrifice others too,

She is a very creepy girl as she sent talks in a creepy way and is serious too
As she takes everything seriously,

And she will do whatever it takes to satisfy the darkness to whatever mean necessary,

She offen follows you a lot to see what your up to as she sometimes break in to your room at night,
