Oichi was captured early in life by a cult attempting to create a method to draw upon the Shadowfell in greater amounts than was safely possible in an attempt to do some not fun stuff. She made friends with one of the other test subjects, but they died soon after by the cult using them as a sacrifiice to summon a demon. Eventually some paladins for a random good alignment god showed up and slew the cultists, but Oichi was mentally unstable by this time due to all the experiments and her latent magical abilities went berserk, which resulted in everyone dying. Using their dying energy, she summoned the demon who was now using her friend’s body as a shell and bound it to her service. Oichi now looks for a way to bring her friend back to life, and seeks redemption for killing the paladins.
