dulcis puella....
Puella dulcis, puer dulcis, nocte tremitis~
The False Hydra a monster that destroys life without a soul noticing, it's lullaby makes you forget, makes the monster invisible to those who hear it, only stopping it's song to eat it's prey.... It will devour an entire city until only dust remains. Once you're gone no one will remember you due to its soft lullaby~
