Growth and Malady

Introduction

Hello everyone! You can skip the intro if you want, it's just some information about the book.

This story is the sequel to my other fanfiction, Second Chances. If you haven't, I highly recommend you go back and read it so you're not completely lost on what happened before this story begins. Second Chances is technically Doukaza fanfic with a lot of extra plot added on.

However, this one is focused around Kokushibo, Muzan, and Rui, with their respective journeys. Mainly Kokuzan, and secondly, Rui x OC (courtesy of Marumakua)

Ages (not all, just some, and I'm basing former demons off of how they look):
Rui (physical): 10 years

Kokushibo (physical): 24 years

Muzan (physical): 20 years

Hinoto: 11 years

Akaza (physical): 19 years

Douma: (physical): 21 years

Tanjiro + Inosuke: 16 years

Zenitsu: 17 years

Ume: 7 years

Gyutaro: 9 years

(I might add more, but if you're curious about any characters' ages, google their age (physical age if a former demon) and add one or two years)

⚠️ SPOILERS FOR SECOND CHANCES AHEAD ⚠️

If you haven't already read Second Chances and don't plan to, here's a list of who was dead by the end of the book:
(Just so you're not expecting someone to show up who's already dead lol)

Hantengu (cause: killed by Muzan)

Gyokko (cause: killed by hashira)

Daki and Gyutaro (reborn): (cause: killed by hashira)

Enmu (cause: canon death)

Sanemi Shinazugawa (cause: excessive strain on body from injuries and demon transformation)

Kyojuro Rengoku (cause: killed by Akaza at the Mugen Train)

Gyomei Himejima (cause: lasting injuries sustained during battle against Muzan)
