Even when things got out of hand, it was no big deal. He could talk his way out of it, so there was no need to panic. Take Muzan, the Demon King, for example. Even with five brains, he still had the intelligence of a complete airhead. That worked out nic 1.1kReads8.4Score143Shelves

   The first book features an original character as the protagonist. Later, he takes Kaigaku back to live with him. During the movie adaptation, Kaigaku is also brought back to Kokushibo. Later in the series, Yoriichi is resurrected, making it a family of three. This is just my personal opinion. Kaigaku's appearance is quite late in the story. The second book features Kokushibo, who later takes Kaigaku back to live with him. The third book features everyone reincarnated in the modern era, but also travels back in time. The protagonist is Mikatsuguchi Tsugikuni, Kaigaku is his younger brother, Mikatsuchi is his older brother, Kaigaku is his second older brother, Yoriichi is his younger brother, and their mother is also reincarnated, making them a family of four. ദ്ദി (⩌ᴗ⩌ )

   1. It's a multi-world story, very mind-bending... 2. It's a CP story (maybe?) 3. Zhuo Xue saves everyone, including Kaigaku. 4. No need to say more, just look at the title. 5. Greatness needs no further explanation, I'm speechless. 6. The protagonist is a half-demon who meets his childhood self, Himejima (not exactly young), and saves Kaigaku in a temple incident. From then on, the young man transforms into a sharp-tongued, arrogant, and eccentric king! 7. Black Kaigaku, a lot of angst, very satisfying, I feel some characters are out of character... 8, 9, and 10 are self-explanatory from the titles. 11. Rebirth story. 12. Arrives in Gotham. 13.

   1-10 are the ones I've been following or have finished watching and found enjoyable. 1 and 2 are about Kaito (Zenitsu). Kaito has a mother who treats him well. In 2, the older Zenitsu accompanies Kaito in spirit form initially, then merges with Gilgamesh. 3, 4, and 5 are about Kaito (Black Kaito). 3 and 5 are from Kaito's perspective. Kaito has a passive ability to rewind time, dying many times tragically, mostly during his wanderings due to various events. He's raised by the spirit of Kokushibo. Kokushibo hasn't appeared yet. 4 is from Kokushibo's perspective; this Black Kaito is a reincarnation, and the Oni faction wins. Among the Upper Moons, only the fourth and sixth died (Hantengu and the Upper Moon Six siblings). Kaito appears later. 5 has a learning system; initially, it involves buying stocks, and later it becomes Black Kaito. This Kaito is very cute. 6, 7, 8, and 9 are without a romantic pairing. Book 6's choices are incredibly good, I highly recommend it. 8 and 5 are by the same author; Kaito has less screen time in Demon Slayer, with most of the plot focused on Sword Art Online. 7 is about players raising kittens, with Kai being the main pet; no other kitten surpasses Kai in importance. 9 is about Kai's rebirth, whose personality is most similar to the original Kai. 10 is about "All Kai," tentatively involving nine characters. Ichiro survives, but due to his critical condition, Kai chooses to turn him into a demon (warning). Here, Kai is the master of the Tokito twins and Zenitsu, and Ichiro is Kai's stepson. 11–19: I haven't finished reading them; there are some parts I couldn't accept, so I didn't continue. You can choose for yourself.

    The first book is incredibly good. Don't be fooled by its title and synopsis. The female lead doesn't participate much in the main plot; she has her own storyline. There might be a Japanese revolution later on, so those who dislike this should avoid it. Kaigaku might be a couple with the female lead, and it's incredibly sweet! The second book, as you can probably guess from the title, is also excellent. It features everyone being reborn. The third book is very unfriendly to the lord, so those who dislike this should avoid it. I'm saying it three times because it's important, but it's also extremely good.
