You could tell who the favorite parent was when their kids were little.
I tried to make the "Nap Time" illustration look like an actual picture, idk how well I succeeded with that, but hopefully it at least looks good lol. I free handed the whole piece, too, which I wouldn't recommend, but I was too lazy to find a good perspective reference. Turned out well all things considered.
From the oldest to youngest, the daughter with the black hair and goggles is Shiori, the daughter with the strawberry blonde hair and pink dress is Marie, and the baby cradled in Engie's arm is Daichi, their only and youngest son.
Erin won a bet that let her name all the odd number kids. Engie got the even numbers. She even thought about letting them have another kid just so her husband could have an equal number of kiddos he got to name, but Engie shot that down, as it didn't really matter to him.
What did matter to him was the simple fact that he adored being a dad, and loved his kids more than anything in the world. Engie would often just grab on of his kiddos, raise them above his head (them squealing with delight all the while) while yelling with joy "I helped make this!!" with the biggest smile on his face. Out of all his creations, Dell and Erin's children were his greatest.
Also, please forgive the google translated Japanese, I still don't know the language, lol
