Mushishi AU (Patreon)

I've been rewatching Mushishi with a friend and then we started to talk about what if a KiriBaku AU? :0

so Katsuki is a smart mushi-shi wandering the land and helping people while being cranky about it, and Eijirou is the random guy who is a mushi magnet and he keeps getting in trouble and Katsuki has to save him

the first time they met, Eijirou was under the influence of a mushi that made it so he could only eat raw meat, and his teeth turned sharp!
when Katsuki cured him the teeth stayed.

(and they became friends)

the second time they met a rare mushi was turning his hair red. it was mostly harmless and Eijirou thought it was pretty cool.

the third time he was slowly turning into stone and more and more unable to move and breathe.
turns out this mushi really like staying in one place, but there's no real cure, he should just see as many different places as possible to counter the effect of the mushi, which Eijirou took as an invite to travel with Katsuki forever~

(edit for extra image of Izuku the mushi nerd, who Katsuki can ask for advice when he runs into an especially troublesome mushi, but he hates asking Deku)
