Hey! I though of a theor for who shiro Loves, its gotta be lil Tian, even tho she said she could make it possible for 2 females to have a baby together, i feel like she was the one to Be pregnant, and if she was with Another female it would be the othwr way around, with Tian hes very shameless, and i can see Him convincing shiro to carry his baby. anyone Else and i feel like the other partner would carry said baby instead of shiro.
Wait, how the heck did Shiro pass the blood and mana test? First, she started as a snowgirl which is a spirit with no blood. And then, she evolved into a Fae which is a different species altogether, and mind you that she keeps climbing the evolution ladder of their species from a Celestial to a Divine Fae. Plus her reincarnation should've messed with her mana signature if not by a lot, then just some but enough to make her mana signature unique to differentiate from her original one.
