   The first book isn't updated much now, but it's good; the second is about someone with memories of the past traveling to the modern era, and might even travel to the Taisho era while sleeping; the third is a new book but good; the fourth is about a modern person traveling to the Taisho era, where Yoriichi, Kokushibo, and Muzan are all demons; the fifth is initially Japanese-themed and dark, later focusing on Kokushibo, and is updated daily; the sixth is all Japanese-themed and dark, with detailed descriptions; the seventh, ninth, tenth, and thirteenth are also good, but I personally don't read them much; the eighth and twelfth are also Japanese-themed and dark, and I recommend them; the fifteenth is a modern-day fantasy/adventure book, and it's good. You can read the others too, but I won't mention them (everyone has different tastes, so I've only posted some books that I personally think are good). [Sending heart]
