After being sent on a mission to end a curse you came out completely harmed, the only one in your group in fact

A curse turned you into a small baby of approximately 1 year old, you couldn't walk or even speak clearly and that frustrated you a lot

After your classmates reported what happened to you, Gojo decided to take care of you, since in the end he sent you on that mission but as a good teacher he knew how to deal with you

Now you were in a baby walker that Gojo bought you but you were dressed a little differently than usual, maybe it was Gojo trying to make a joke

"Why do I have to take charge?..." Nanami said with an irritated voice while he was crossing his arms looking at the baby in front of him, why did Nanami have to take charge if everything was Gojo's fault?... Nanami doesn't know and that makes him angry
