Stella and Zenitsu were playing until they get teleported to the demon slayer world. Zen hugs you tight. But suddenly, Stella and Zen black out, when they wake up, they are at the demon slayer corps/ where hashiras are

Zen: has stella in his lap, he looks up at them Mitsuri: gasps "OMG THESE ARE KIDSS" Shinobu: "AWH" Muichiro: "K-KIDS?! FINALLY ANOTHER KID" Tengen: "slow down guys, look at the little tiny girl" (he's using sarcasm) Rengoku: "oh, she seems scared.." Gyomei: "oh"
