A long time ago... there was ascension.
The succubus graciously gave her life for the kind little princess, she took it all, to ascend to what she was fated to be, a goddess.
She knew that this power was to be used for good and not evil, so a vow she made, to eradicate all succubi that hunted people.
The newly born goddess would make the noble and kind sacrifice for everyone, for she would absorb and contain all the corruption, she would be the holy one.
The goddess of love, the goddess of compassion, she who would come at anyone's cry, for she is Clerys, the one and only that deserves to rule everything under the blue sky.
