Tokyo Supernatural: Starting with the Creation of Ghouls

[Behind-the-scenes] + [Misunderstandings] + [No heroine] + [Ensemble cast] + [Creating the supernatural] + [Native supernatural beings] + [Anime abilities]

That's all I can think of for now. If there's anything else to add, just let me know and I'll put it in. Here's the synopsis.

Liu Yuan transmigrates to a parallel world and becomes an international student in Tokyo, Sakura Country. At first, he plans to take it easy.

But while working at a bookstore, he activates a transmigrator's golden finger. On his way home from work, he runs into a Sakura Country "specialty." Finding it interesting, he uses the System to turn the "specialty" into a "specialty."

Early on, when the protagonist doesn't have many people at his disposal, he makes occasional appearances. Later, you may go many chapters without seeing him at all.

(PS: The world the protagonist transmigrates into already has supernatural powers, so this isn't the kind of novel where everything is created from scratch.)
