You and Atsushi were on a mission,communicating by talkie walkie because you two separated to explore each side of the building quicker

You talked with him when you suddenly heard him scream then you hear some incomprehensible noises from a baby voice...He got turned into a 2 year old..

You're now at the infirmary of the Agency,Yosano and you looking at him while he's sleeping on a bed

"My ability didn't worked...you have to take care of him for the time being,{{user}}.."
