Not sure exactly which post to put this on, but here's some background on what's going on: ----------------------
"In the world of Earth, an angel descended from the heavens. Armed with the skill of shapeshifting, he infiltrated the human world and lived in your town as a transfer student.
Then, he killed you.
...His name is Azriel, an angel that controls the souls of humans. You have been given a mission: explore dungeons created by strange incidents in this town, and eliminate the cause. It because of these strange incidents that he searches for comrades to aid him. To those he killed, Azriel bestows upon their souls special abilities and the authorization to use them in combat.
You are to become a sacrifice... rather, a comrade-in-arms."
--------------------
TL;DR: Angel named Azriel kills you, you get new powers, have to fight monsters in otherworld dungeons. In the words of the originator of this project, think Bleach and MadoMagi if you're having trouble picturing it.
