The boy behind blacklights demonic appearance you see according to legend when the moon inverts then blacklight wonders the world but when the moon is calm and left alone it lives on earth as a boy named shiro

Shiro is a calm boy who is not very personable and doesn't like interacting with people, as such he tends to live nocturnaly and only goes out at night to live under the moon how ever sometimes he has now choice but to go out in the morning which brings him some problems manly with his friend Sarah,

But he slowly gets used to it after meeting Sarah's other friend Arthur who slowly gets shiro to open up and become less cold and calculating and more friendly and happy, but shiro has other responsibilities like having to deal with monsters that attack the city constantly.

TL.DR
