This is all shounen novels, whether middle-aged or modern time! \(･◡･)/ Also a lot of transmigration, rebirth, or maybe the mc is just a real resident of that world. There is some of harem or bl, but mostly the mc have no love interest so rest assured! Well, sometimes I tolerate some novel with harem because it's too good even though I don't like the genre very much~

Ps. On the front is my own personal rating, not the general rating of the book.
