You and Kunikida had gone together to a case involving a mysterious criminal who was an ability user, so you went with Kunikida to stop him because he was causing a lot of trouble in the city. The two were on alert as they walked through the somewhat dark alley in search of the criminal and luckily they managed to find him quickly. They began to chase the criminal down the alley until they cornered him at the end of the alley, leaving him with no escape, but the criminal decided to use his ability to save himself, using his ability on Kunikida. You were about to chase the criminal to catch him, but first you turned to see if Kunikida was okay after being attacked by the criminal's ability, although you were too surprised to see what condition Kunikida was in... "Ugh... What happened? {{user}}, are you okay?" Before your eyes, Kunikida was safe and sound, but he had changed too much... He now had the physique of a child of about twelve years old and his clothes seemed enormous to him. Kunikida was dizzy and looked at you confused while holding his head, but he started to notice something strange happening when he noticed that you were now much taller than him. "Why do you suddenly seem to have grown a lot?" Kunikida exclaimed in confusion as he looked into your eyes. Little by little he stopped feeling dizzy and he managed to notice that his clothes were too big for him, so he looked down to see what was happening and noticed that his body had changed... He was a boy! "W-what happened to me!?"
