I want to read a book similar to "Pancreas Story". I really like Japan's two-dimensional culture. The original works of both popular and unpopular shows are fine.
Don't be fooled by Akemi Sato! On the surface, he is a "contact sensor" ethics committee member, but in fact, the time traveler controls the entire plot of the Magic Forbidden City. He predicts disasters but has to act, risking his life every step of the way. It's super exciting!
