    Books one through three are about a black Kaigaku. Book three is about a demonized Kaigaku who travels back in time, so there are two Kaigaku. Book four is about Kaigaku's rebirth and atonement, including a demonized transformation. The main story is complete, and we're currently updating Book five, which features an original female lead. Kaigaku has memories of his past life, and all three members of the Raimon sect were struck by lightning. It's a funny story 😁😁 Book six is about Kaigaku transmigrating into the DC universe. Updates for this one are a bit slow, so it's best to let it run its course. Book seven is about a soul transmigrating into Kaigaku's body (basically, he transmigrates into himself). Kaigaku obtains a system that sends him to redeem others. Book eight is about Kaigaku encountering Zenitsu after his demonized transformation. Neither of them joins the Raimon sect. They then become third parties. Basically, it's quite sweet.

There's an alternate story with a Demon Slayer Corps "what if" scenario. 4 is about Zen Kaigaku, who was prematurely turned into a demon during his wanderings. He later met Zenitsu and continued wandering, never going to Momoyama. It's a story of two demons, who become human again after a great battle, forming a third-party faction outside of the human-demon alliance. 5 is about modern-day Kaigaku returning to the Taisho timeline through a holographic game, unlocking various "what if" scenarios and different possibilities, and revealing the bond stories of various characters (it's been played out in a very complicated way). Moreover, the change in the human-demon alliance is actively driven by Kaigaku, not passively! There's also a hidden storyline within the game's timeline: because the bond stories involve going back to the past, and different people's bonds exist within the same world timeline, they will be remembered and genuinely altered to some extent!

    The first book, "The Divine Arrival," needs no introduction. The others are also excellent; I've been eagerly awaiting updates and rereading them countless times. Most feature cunning and adorable characters, and they're all cunning protagonists.

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.
