Spritzer

A spirit of the dead. A floating blue ball with a green haze that is loathed due to its strange appearance. In the past, people who would see spritzers in the dark often mistook them for disembodied heads with pale faces and disheveled hair. They are actually monsters born out of the regret and resentment felt toward the living, being no bigger than a human fist at first, growing larger the more bad emotions they absorb from the dead.
