Ryuunosuke also tends to be a bit clueless about certain things of the world due to her being motherless from a young age. Her father's extreme selfishness rampaged as he liked, telling Ryuunosuke lies about anything he wanted since she had no way of knowing any different. (Such as saying that a certain food is poisonous just so he can safely eat it while she's not looking, or that Valentines are bad so he can take all of hers for his own purposes.) Since associating with people other than just her father, this has led to a number of embarrassing situations for her (while also clearing up much of this misinformation), as well as causing her to lose faith in almost anything her father claims now. About the only thing he can consistently trick her with is information about her mother, of which he never really reveals anything, using it as yet another way to trick or just make fun of Ryuunosuke.
