|“||Uesugi-kun, you've really done it this time. However, I will not hand my daughters over to the likes of you.||”|
—Papa Nakano's monologue.
Maruo Nakano (
Ebata is the Papa Nakano's secretary and occasionally driver. Due to Papa Nakano's lack of time and attention towards his stepdaughters, Ebata is assigned to take care of the quintuplets.
Fuutarou's father, Isanari, somehow has a relationship with Papa Nakano prior to the beginning of the series. Through Isanari, Fuutarou was able to land the job as the quintuplets' private tutor.
Despite choosing Fuutarou as the quintuplets' private tutor, Papa Nakano has a hostile relationship toward him. He denies Fuutarou and objects him marrying one of his daughters. In the future, Papa Nakano refuses to show up at his daughter's wedding with Fuutarou until Isanari reprimands him.
- "Ebata, it's such a joyous occasion for all of my daughters to clear their exams. I wonder if I'm smiling? ... I see. As their father, that's a given."
