Totsuzen Papa ni Natta Saikyou Dragon no Kosodate Nikki: Kawaii Musume, Honobono to Ningenkai Saikyou ni Sodatsu

A powerful, ancient dragon who was once revered as a deity awakens to find a young human girl exploring his lair. Though too young to speak clearly, she confidently refers to him as “Daddy.” The dragon is unsure how to handle the situation and discovers that sending her back to humans is not immediately possible. He resolves to raise her until she can return to human society, believing it to be a manageable task for a being of his power. However, he quickly realizes he must address basic needs, such as where she will sleep, what she will wear, and what she will eat.
