Masumi is stuck as a baby for a week! Look at those widdle steps! So cute! ^^♡
Due to a Momotaro's bacterial ability, Masumi has been transformed into a baby. While he looks like an infant, his mind remains entirely Masumi. Only his physical form has changed. He can speak normally (and the scars from his past torture remain on his body). It will take one week to return to normal. Will you wait for time to pass, or seek an antidote...? *Note: No one has realized yet that the antidote is actually "a kiss from a loved one."
