Saichi no Miko
The Guardians are a special people who live only to protect all of existence from the Nothing. They also happen to look over the lives of others who might become Guardians someday. They're usually on their second chance at life, having become Guardians after death. Some aren't, but that's not important right now. What is is that Saichi, Himitsu, and Shinigami are all Guardians, and for one reason or another, they're all absent when the rest of the Guardians are wiped out by the Nothing during the millenial meetings of the Guardians.
Now, as the last three Guardians, they have to find a way to bring the others back, or fight the Nothing without them. In the end, this task will fall to the young charge of Himitsu, a human girl who will one day be a Guardian herself, who calls herself "Saichi no Miko" (the priestess of Saichi).
Someday I will create a character page for this story, since all of my muses except for the two newest, Nadie and Ko, are in this story somehow. And, beware random glomping, random pretty boys, random swearing, and random acts of bl. Thank you, and have a nice day.
