    These are all great! I'd like to know a few that aren't very popular... But are really good! There's also a new book called "The Ordinary Life of a Kind-hearted Person," you can look it up, it's good too! Thanks!

    They're all about Kaigaku. The first one was serialized, and there wasn't much written yet. The second one was super good, and it's almost finished. The third one has an original female lead, but she's not Kaigaku's love interest; she's a very abstract character, and quite funny. The fourth one was also pretty good; I remember several characters later on formed couples with Kaigaku, which was quite nice. The fifth one is about Kaigaku being the child of Inari, reborn and protected by the gods, but the author updates it relatively slowly. Books 6, 7, and 8 all involve Kaigaku's rebirth. The ninth one is also super good. Overall, books 2, 4, and 9 are the best.

After spending thousands of years in Hell, he returned to the past in exchange for saving people and changing the tragic endings that had left him with regrets. He thought he had been reborn, but in reality, this was his second go-round. Slow-paced. No CP, ship whoever you like. Misunderstandings abound. Obanai Iguro, who is afraid of men. Sabito and Kaigaku, both motherly types. Yuichiro Tokito, who is constantly stalked by perverts. Gyomei Himeji 1.2kReads9.0Score112Shelves

    I remember these are all examples; I won't recommend the others since Kaigaku doesn't appear much.

Kokushibo takes him in, and then he goes around causing trouble (crossed out). Expect scenes of him watching over Doma and Kotoha, kicking all sorts of characters out of the story, rewriting the temple incident, and more, all appearing at the appropriate points in the timeline. (Don't ask how.) There are two Kaigakus in the past timeline, and the viewpoint will keep jumping between demons and humans. Scene to look forward t 395Reads8.8Score105Shelves

They serve as ritual objects and are also used to pray for protection. But Kaigaku doesn't believe in so-called gods. If praying to the gods could grant you anything, why would temples let the poor inside? It wasn't until his blood awakened those mysterious beings that Kaigaku learned the gods might actually exist, and that they had granted his wish.

    The first three books are all good, especially the ones with no romantic pairings. The last three are also excellent. You should check them out. The last one is a crossover of sword and chaos.

You can think of this as giving Kaigaku a lucky-charm cheat. He won’t be redeemed or turned into a demon. This follows the Sound Hashira route.) Inadama Kaigaku was a man both hateful and pitiable.
