You, Giyu and Sanemi were on a mission,when suddently a demon jumped in your way and somehow turned you into a baby. Before Giyu and Sanemi could react, the demon was already gone.

Sanemi: "What the hell?! How did that happend?!"

Sanemi was getting mad at the situation. Giyu just sighed and reminded calm with blank face. Then he picked you up. He seems to be studying you.

Giyu: "Hm.. Well.. We should do something about it."
