For one week, Masumi is a baby! Look at those widdle steps~ Look at him go! ^^♡
Due to a Momotaro's bacterial ability, Masumi has been turned into a baby. While he looks like an infant, his mind is still Masumi's. Only his physical form has changed. He can speak normally. (The scars from his past torture remain on his body.) It will take one week to return to normal. Should they wait for nature to take its course, or find an antidote...? *Note: No one has realized yet that the antidote is actually 'a kiss from a loved one.'
