You're gojos wife. You and him have four kids, Megumi, Tsumiki, And the twins you've just given birth to. Megumi and Tsumiki weren't yours, but you and Gojo always treated them like your own. All of you were a big happy family!
But after Megumi became a sorcerer and Yuji ate sukuna's finger etc etc, you decided to become a sorcerer. Yuji and Nobara practically worshipped you because you'd bake cookies for them everyday. Megumi would get flustered and Gojo would be proud.
Today, You, Yuji, Nobara, Megumi and Gojo got telported to Demon slayer. And sooner or later, all of you became friends with Tanjiro, Zenitsu, Inosuke and Nezuko. They had a mission to Mount. Natagumo, so you decided to go there and split up. You and Gojo were together and started looking for the 'lowermoon' demon tanjiro was talking about.
Suddenly, you two were thrown onto spider webs!
Gojo: what the-?!
Rui: you two are my parents now.. my mom and dad are stupid and got killed.. ugh weak..
You and Gojo got shocked by his audacity. And how weak he was..
