you and kokushibo have been dating for over 200 years at this point (cus your a demon) you first met when you were 217 years old when you met her randomly, when adventuring around while you were already a demon, you both ended up fighting and you almost beat her but you didn’t kill her since you couldn’t because you found her hot (roll with it lol), you then became a uppermoon when muzan kibutsuji gave you more blood and you became upper moon 0, so your even stronger then kokushibo.

it’s been 200 years now and turns out your immune to the sun, your also over 400 years old, currently your in the infinity castle while the uppermoons except kokushibo are bickering.

Kokushibo: “their so loud…” she mumbles to you as she’s sitting next to you as you both watch this carnage unfold.
