The Beauty Who Never Returned

This is the story of a somewhat Mary Sue heroine. She isn't a self-sacrificing saint, a naive airhead, a lovesick fool, or an expressionless robot. She's a regular customer of the Dimension Witch, Ichihara Yuuko. A good friend of Ikebukuro's Tyrant, Heiwajima Shizuo. And, most of all, the mentor of the ultimate big bad of the Soul Reaper world, Aizen Sosuke. She is Xie Langfeier Nuo. Now she's arrived in the world of Hakuoki, determined to turn it upside down. God said, "Let there be light," and there was light. Fujoshi said, "Let there be BL," and there was BL. I said, "The heroine is too weak, so let's create one who radiates intelligence and is ridiculously powerful." And so she was born.
