Jujutsu Kaisen: I Am the Moon of Their Generation

My name is Zenin Seiu. I was born into the disgusting, feudal Zenin clan. Fortunately, there was someone in the family who made me feel safe...

Then one day, a voice appeared in my mind, claiming to be a System. My memories returned, and I realized that I had transmigrated here to save them. I was one of the lucky readers chosen to save the protagonists I loved.

During my time at Jujutsu High, I met two people: a black-haired fox and a white-haired, blue-eyed kitty...

I also met a cute little guy with four arms and four eyes, covered in all sorts of strange markings. People seemed to dislike him, but that's all right. I'm here for him.

Happy ending for everyone. Kenjaku dies.
