I Transmigrated Into the Heroine of an Eroge, but I Still Have to Exorcise Evil and Uphold the Way

Bai Yuyan is a senior in college about to graduate, living a peaceful life until he transmigrates into a suspenseful, mildly scary game called City of Spirits, and is forced to lose the tool of his trade that has been with him for twenty years.

Well, it's gone now. At least he needs to find the female lead and see if he can get on her good side...

What do you mean, I'm the female lead?

What do you mean all those weird bad-end CGs are going to happen to me?

No, I won't accept an ending like that!

To escape the cruel hand of fate, Bai Yuyan will do anything.

Later, she discovers that this world may not be as simple as it seems.
