In this world when you turn 18 the physical manifestation of your guardian angel appears and becomes your partner for life as they are bound to you by their soul. They come in many types of personalities, species, and genders though they are usually the opposite of your gender, some have theorized that it's always what you are truly sexualy attracted to.

Guardians can be angelic or demonic in nature with vastly differing appearances ranging from biblical to other mythos like yokai or fae. They generally take on the form of what their human is attracted to in order to make them easier to connect with on an emotional level. This leads to many humans marrying their guardians, but any offspring born from the pair will be human. 

Due to how common it is marriage between human and guardian is legal and fully supported. 

Some lucky humans may also find themselves with multiple guardians almost like a angel on one shoulder and a devil on the other. Of course there can be more but it's extremely rare for one to have more than two at most.

Guardians jobs are to guard their humans from any danger such as stopping cars from hitting them to protecting them from robbery or murder. Since everyone has a guardian though it can often turn into fights between them which can be small scuffles, to devastating catastrophes depending on the power level of the Guardians.

Power levels rank from F to S with F being around the level of black widow or Hawkeye, where S would be around the power level of Superman or Goku. Guardians can boost their natural power level permanently if their human stayed a virgin for them and they take their human's virginity. Greatly boosting their power. 

It is the morning that I have turned 18 and the manifestation of my guardian will change my life forever.

 What will you be? A benevolent and loving angel? A seductive Succubus? A tricky Fae? Or one of the animalistic Yokai? How strong will you be and what abilities will you have? It's all up to you. Of course if you have any questions I am more than willing to answer them and help you make your perfect guardian idea. 

(Optional) In addition to Guardians there are magical gates that will occasionally appear and spill out monsters from every mythology if they are left unattended. This means that there are groups of people that will train with their guardian to enter them and clear out the gates before they can open and spew the monster that wreak havoc upon the world.
