Race notes

[Nan-Yo]

Human:  Nothing special needs to be said at this point.

Human (enhanced): Tend to live several years longer, have extra resistance towards disease.  Easily recognizable by hair and/or eye color.  They have been
around long enough and their differences subtle enough that they tend to be treated normally and if they get any extra attention it will be due to their
appearance.  At this point they have been around long enough that ordinary humans don't find them unusual and their non-appearance differences are subtle
enough to rarely be noticed.

Human (Four Lines/Avatar): Upon death they ascend to become an angel if they remain loyal to their cause, demons if they betray heaven.  Otherwise they
are comparable to the enhanced humans.

Godling: A catch-all for people with varying mixes of human (normal, enhanced and four lines), angel, half-angel and potentially god and demi-god blood.
They are further enhanced by lifelong physical, magical and spiritual therapies.  Most are born through a breeding program ordered by heaven though a few
come from entirely willing parents.  Some are naturally immortals, others make an ascension similar to those of the Four Lines.

God: Immortal.  Primarily spiritual beings, their physical bodies are more for convenience of interaction with lesser beings.  All aspects of their physical
form can be changed on a moment's notice.  That said they do tend to develop gender identity after a while and will rarely if ever willingly take a body of
the opposite gender.  They are not invincible, though even harming them would require divine blood or a weapon specifically designed for such a purpose.  
They could even die though it is unlikely anything but another god could do so.

Demi-god: Immortal.  Rare due to the gods' understanding the trouble that could come from breeding too many, though with the Uomizu family and the obvious response to it, their numbers are starting to grow.  Even the gods in Heaven are seriously consider parenting a few each (this will not become relevant until Bianka's time).

Angel: Immortal, tend to be emotionally cold.  Most live in Heaven, some act as guardian angels to important chosen mortals and others act on Earth while
pretending to be human.  More physical than spiritual, but with no need for food/drink/air/etc.  They are tied to their bodies.  Can be killed, but usually
not worth the trouble.  Wounds usually regenerate before they can add up.

Demon: A catch all name for beings that are tied to hell in some way. Some are immortal such Imps, Djinn, Gargoyle and the fallen angels transformed by extended periods in hell, (though they are capable of breeding), but other species such as Succubi and Ogres are not.

Half-Angel: Immortal, they have a chance of inheriting angelic coldness.  They do require most of the same needs as humans, but need less and go can go
considerable lengths of time without them.

Zan/High-Elf:  Not immortal, but they live for thousands of years.  As survivors of the old universe they are biologically incompatible with most races
(gods/demigods could force a pregnancy, but no one else could).  Their reproductive anatomy is different than the other races (still considering the details).
On the rare occasion a human sees it, they will usually claim it is a birth defect of sorts.  Sex is still possible but may not be comfortable for one
or both participants.

Titan: Immortal.

Vampire:

 

Fairy: Connected to specific points and forms of nature, can get sick or die if they move or said spot is damaged.  Land based ones blend in with humans.
Sky based have wings and at least some of the sea based ones have varying degrees of fish-like qualities.
