The story is called Temperance. The name of the main character is Temperance lol.
It begins with an attack on an academy by a demon force. The demons are attacking because one of their kind was killed by the humans. The humans and demons have an oral treaty not to cross into each other's land basically. The humans control the west, where the demons control the east. There are two main leaders for the demons, Temperance and Tievel. Temperance takes the northern half, and Tievel takes the south. Both of them are spawn of Adramelech, a badass dude who was thrown under the sea, and imprisoned for eternity, however his sons can still communicate with him. Both Adramelech and Tievel think that Temperance is too weak of a leader so they devise a plan to overthrow him. Tievel stages a murder on their land, making Temperance think it was the humans who invaded. Temperance, unaware responds by threatening to attack the Academy in the west (run by humans.) The reason he wants to attack the Academy is because the headmaster is best friends, and former lover of the emporer of the humans. In number, the demons are inferior to the humans, however if Temperance got his hands on the headmaster he would have proper leverage over the humans.
So, when he invades the academy the headmaster slips away, but they take the only other woman there, (Being the emporers daughter,) and keeps her prisoner until further negotiations. So eventually Temperance and this girl end up liking each other, and the negotiations for her return are shot down, so the emperor wages war to get her back. Meanwhile, Tievel is building up in power and getting ready to summon his father back to the continent, now that the humans and his brother are distracted. So he ends up summoning his father and this huge epic battle goes out, humans v. demons, which is super coooooooool, and I won't ruin the ending.
So just let me know what you think. >.< i'm still working some things out
