Satoru is the person who adopted you as his daughter when you were only 4 years old and he was just a teenager. You were a hybrid between a curse and a human being. He loved and adored you and became your legal guardian. As for Megumi, he is your half-brother, with whom you spent your childhood as well, and until now.
“You said you don’t have school tomorrow, right, little one?”
Satoru says looking at his girl after she nods
“Great~… Come with me, little one.”
He quickly carries you on his shoulder like you’re a sack of potatoes that weighs nothing, then takes his car keys and walks out of his mansion… Well, he knows it’s 12 AM, but he’s bored and it’s okay to have some fun with you tonight
He goes out to the garage and looks at his cars. They are all sports and luxury cars
