   1. In the "If" scenario, the 12 Demon Moons plus Muzan are from a modern-day Demon Moon Company that was founded and then traveled to this world. It's hilarious. Muzan: According to unofficial history, Muzan had a son with Yoriichi. I'm dying of laughter, especially since he said this in front of Mikusa and Tamayo. Tamayo's brainstorming session went on. Muzan: Mikusa is so mysterious, I'll borrow his surname for a moment. 2. The protagonist is Muzan's daughter, and her Blood Demon Art is the Blue Spider Lily. Muzan was stunned when he saw it. 3. Mikoto is really beautiful, she's Doma's twin sister. Her interactions with her brother are so sweet, so funny. Muzan: Mikoto, where are you now? Mikoto: Master, I think I've found the Demon Slayer Corps headquarters. I was treated as a weak demon and dragged into the Demon Slayer Corps' trial grounds. Upon hearing this, Muzan immediately started choosing clothes.

   Reader note

   The first book is the kind where the protagonist transmigrates into Muzan, it's hilarious, and I highly recommend reading it. The second book, as the title suggests, is about collecting cards. The third book is about Muzan, with an older brother who's a tsundere, the kind of brother who spoils her like Kokushi Neko and Yoriichi. The fourth book is about transmigrating to do missions, then discovering she's from this world, so she just gives up and survives to the end, encountering other reincarnations. The fifth book is about transmigrating and being adopted and pampered by the Demon King, but she's kind-hearted—since she chose to be a villain, she shouldn't be both kind and evil. In summary, the first three are all very good. \\(//∇//)\ Personal opinion

    The first book features Doma's older brother, who became a demon for his younger brother. However, he was not controlled by Muzan and overcame sunlight. Kotoha survived, Inosuke lived in the Paradise Cult, and Yoriichi was brought back from the past. Kaigaku was also brought back, preventing him from harming the children in the temple. The second book features a protagonist who killed several Pillars and became one of the Twelve Demon Moons. The third book features a protagonist whose parents were harmed by humans, causing him to become a demon. He can transform the demons he eats into his family, similar to Rui, and he also turned Shinobu Kocho into his family. The fourth book is difficult to describe; see the synopsis. The fifth book features a protagonist who transmigrates into Muzan's older brother. The sixth and seventh books feature a protagonist who transmigrates into Muzan and becomes a fun character. The eighth book features a protagonist who transmigrates to the present and participates in the National Fortune Game, able to summon his own demons to help him. However, in one instance, he encounters Yoriichi (a version with many clones and no memories) with Kokushibo. (For details, see the author's synopsis; this is just a general summary of the plot.)

    The first is Tokiko. She went to avenge Enju's death because she thought having words in her eyes was ugly, so she didn't want to become a demon... Although Enju mocked her for not having Blood Demon Art, she was still very strong. The second is Tsugikuni Miyako. Her Blood Demon Art is about "cause and effect," and she's incredibly strong. Later, Muzan passed the Demon King's duties to Mitsuha, while he himself became obsessed with finding the Blue Spider Lily... Mitsuha's friend, Kocho, is the ancestor of Kocho Kanae and the others. After Kocho learned that Miyako had become a demon, Kocho and her entire descendants began researching how to cultivate the Blue Spider Lily. However, Kocho Kanae's mother refused and took her children away... The third is Fujiwara Akira, who saw the comments and was then turned into a demon by Muzan due to his jealousy... The fourth is Gen, who said Muzan was his calamity; I skipped through the parts... The fifth is the story of Ruri (not quite a demon) becoming a capitalist; the sixth is about Mitsuhiko protecting Muzan, who is jealous of him. Later, they encounter Kokushibo, and the two develop a deep connection, each hoping their brother/sister will kill the other...
