This is about demons.

Demons need human's blood to survive.

They need human's blood once a week, or they'll be weak.

                                                                                    Sometimes, there is such thing as half demon and half human.

The demon can do two things.

Either kill the humans for blood, or make them be like them, demons.

When demon's eyes turns red, it means they are really angry.

When their eyes turns purple, they are mix with anger and sadness.

Only other demons can see the colour of their eyes, but not human.
