Fukai Mori (sesshomaru x reader)
Hundreds of years ago, a Dog demon clan called the Amaterasu ruled the East. Their power rivaled the Dog demons of the west, and in hopes of shedding peace, the two heirs from each clan would be wed- that was until the Amaterasu disappeared without a trace, leaving the arrangement in the dust.
Many decades later, the demon who was once in line for the tribe's throne has suddenly appeared, and so she travels, searching for the reason her clan disappeared along with her own memories.
Now she travels with a Daiyokai, an imp, and a child, in order to complete this task- encountering new enemies, and old ones.
