Akatsuki Babies

Mutsuki is the spoiled teenager of his self-centered, meat-loving dad, Uzuki! They're loaded! Or at least they are until Dad's bad management sends his company down the toilet. Desperate to escape vicious loan sharks, dad mixes a tonic to make him younger with some tequila, and BAM! He's three years old again! Now Mutsuki must fend for himself and the dad he's wanted to punch in the face his entire life. What happens when the father becomes the son? Or maybe the little brother?
