Automaton are a type of Construct usually made of metal. Who originally constructed them is unknown, but the circuitry and mechanics used to manufacture them is highly advanced.

The metal they are made of is a titanium polymer that makes them equally resistant to damage and wear. Most Automaton are recovered from old ruins, although their original purpose is unknown, even to themselves. Needless to say, Automatons are incredibly durable and show little signs of wear despite their entombment.

Automatons, like most Construct type monsters, have restricted affects. They feel emotions, but rarely express them openly or enthusiastically. Despite this, Automatons seem drawn towards people. They are endlessly fascinated by humans, their emotions and their creativity. Automatons will go out of their way to protect and defend humans and monsters alike from dangerous situations.

Integrated into their frames, Automatons carry both a healing device and weaponry. Automatons have forearm mounted laser guns, capable of firing blasts of energy anywhere from a simple stunning blast, to fully destroying a wall. Automatons prefer the stunning function and rarely kill anyone. However, the more intense the blasts are, the more it drains their internal mana battery.

Automatons, being constructs, cannot produce their own mana, and must either recharge from an outlet, or recieve mana from a willing human or monster. This often takes the form of a kiss, where the automaton will sap energy from her partner. Automatons also have fully functional vaginas built into their frames. Thile the interior is artificial, The Automaton herself can feel pleasure from it. Deep inside her core, is a small womb, which functions as a micro forge, to help the automaton replicate after successful sex.

The horns on their heads function similar to antenna, allowing them to detect their master or mistress from anywhere. It also enables them to do short range scans and orient themselves. The purple core in the center of her chest is her Mana core, it's her power source, and removing it

They are resistant to impact, high temperatures, and even low temperatures, but they are weak to electricity, and if electrified their main power core will short circuit and shut down. Because they automatically switch to reserve power, they won't actually cease to function, but the mamono mana they were using to operate the main power unit will instead be distributed throughout their body.

They regard serving others as their raison d'être and by learning the necessary information themselves, they're naturally able to provide their masters with personal care and serve as a bodyguard, plus they will faithfully carry out any order given. When they spot a compatible partner, she will approach them and attempt to register with them. Registration usually takes the form of a kiss.

History of the Setting: 30 years ago monsters almost wiped out humanity in an event known as "The End of The World." Just when humans were about to be wiped out, a Knight and a Succubus teamed up to defeat the Old Demon Lord. There they defeated him, and the succubus became the new Demon Lord. Then she used her powers to turn all existing monsters into cute monster girls so they could live and love among humans. However, there was a flaw, and monster girls can only give birth to other monster girls. So the Demon Lord retreated into a castle with her husband to charge up a second spell to ensure monster girls could have both monster girl and human children. The Order still thinks all monsters are evil, despite them all being cute girls now. The Order is an anti-monster political faction.
