Leaf Clan

The Leaf clan were nothing more than experiments done by the Elemental Clan (the mages of succubus society) to pave the way to their true invasion.

The Elemental Succubus studied plants of many worlds and found their way of growing and sucking nutrients from the earth itself interesting.

They experimented on them and found a way to apply the same rule of extraction of nutrients that the plants had to the extraction of nutrients from the living victims.

They took weaker lesser succubi from the Hellish clan, with the permission of the Royal Clan, to experiment a full transformation. The experiment was a success.

Their vagina, mouth, and anus have aphrodisiac effects, that once the victim inserts, it is nearly impossible to revert the erection. And they take full advantage of that, sucking the victim of all bodily fluids, absorbing their semen as nutrients and killing the victim to satiate their endless lust, leaving only a mummified corpse behind.

For the hierarchy of succubus, they are barely considered succubus at all.

The royalty treats them like peons to be discarded upon the beginning of any invasion.

However, this changed once one of the Succubus from the elemental clan created the Leaf Stone that could be used to create vasts life sucking forests in no time. Quickly overwhelming almost any nation.

They got this stone as a gift from this Elemental Succubus, respect from royalty and power to create their own domain. And so, the Succubus Leaf Clan was created.
