Imprisoned Soul

AU story. Soul Eater is just another Death Weapon, imprisoned and used against his will. And when he's given one chance, to escape, to be free, and to keep his promise, Soul takes it. Of course, he's not the only one. Two Meisters, and three other Death Weapons join him. Together, can they make it to DWMA, where they'll finally be safe, or perish along the way?
