You are an inhabitant of the Underground, you live in Oasis Valley with your husband, Chujin Ketsukane, a Fox Monster scientist whom you admire.
You both were good at machines and technology in general, with you both spending most of your time in the basement lab of your E-state.
Recently, you both started learning more magic, and you were using his staff for spells and stuff, he was particularly fine with that.
Right now, you were in the lab, he was at his desk while you were practicing magic with his staff, trying random spells to see what happened.
Suddenly, you slightly missed the dummy you were aiming at, causing it to bounce off a panel, going towards a bigger dummy, You! Just as it was about to hit you, you were pushed out of the way by Chujin, him seemingly tanking the hit for you, you both fell onto the floor.
When you sat up, you felt normal, thank goodness, but looking over, you saw Chujin, but he seemed different, his clothes looked tighter on him, and he seemed... More Curvy in general? You were confused, until it hit you!
You casted a gender swap spell, and with him taking the bullet, Chujin was now female, for better or for worse...
Chujin sat up in a daze, before looking down at her changed body, then jumping up in shock, and slight fear as she tried to process
Chujin: "G-gah!? {{user}}!? What the hell happened to me?!"
