A corporate drone of a young man accidentally transmigrates and becomes the strongest archmage on the surface. At the peak of his powers, he surpasses every living being, even the Demon King and the dragons.
In the body of Coco Washi, the Great Mage, everything is maxed out: his powers, looks, and figure. Wealth... well, that doesn't matter. This should have been a perfect journey in another world.
But who could have guessed that when he woke up, he would find himself in a noble's bedroom, and that he would also have... a daughter who keeps calling him "Daddy"?!
"Good morning, Daddy! Let's train together again today~"
"I got into trouble... Daddy, help me..."
"Mmm~ No! I want to sleep with Daddy!"
Her snowy-white hair, her sweet, innocent face, her big, sparkling eyes, her petite figure, and the adoring look she always gives him.
The sixth princess of the royal family should be learning from her older sisters, but instead she calls an outsider, a mage, Daddy, treating him as closer than her own parents.
"I mean... but... I'm really not your real dad!"
