Yōto Yokodera is a second-year high school student who is arguably the biggest pervert at school. His problem is that he is not good at showing his real emotions. One day, his equally perverted best friend completely transforms and gets rid of his "impure thoughts"; a feat he attributes to the power of the statue of the "Stony Cat". As the rumors suggest, by wishing upon the statue and giving it an offering, one can wish to remove a personality trait from themselves that one does not wish to have anymore. However, this will remove the unwanted trait and give it to someone who does need it.
As Yōto is making his offering to the statue, a girl named Tsukiko Tsutsukakushi arrives to make her wish to be able to be more like an adult and not show her emotions so easily. Both of them wish upon the stony cat and to their surprise the next day at school, Yōto is unable to tell a single lie, and Tsukiko is unable to show any sign of emotion whatsoever. After realizing that they do not like the change that happened, they work together to try and find out who has received their trait that was taken away in order to get it back. They meet Azusa Azuki, an attractive second-year girl who has just transferred into their school. She is always being confessed to by many boys in school, but she has no friends and is always alone. Yōto finds out that Azusa is the one that received his unwanted personality trait and tries to get it back.
Yōto is the main protagonist and a second-year in high school. He is portrayed to be secretly a huge pervert yet he cannot express his inner self truly because his deeds are always misunderstood, due to being unable to say what's on his mind. He even claims that he joined the athletics club so he can see girls in swimsuits, but even that is misunderstood due to his actions. So he heads one night to the Stony Cat statue to wish for it to take away his façade, since it's getting in the way to life freely. However, it isn't until he wishes on the Stony Cat statue to stop lying, stop putting up a front, and stop dodging questions that causes him to get into trouble. It seems that the Stony Cat statue granted his wish, but granting it precisely as he wished it. So for a time, he loses his 'façade' (tatemae) to the Stony Cat statue (by given it to someone else who needs it), which he later recovers it back from Azusa (who had gain it), but during the time without his façade, he openly speaks everything on his mind, including all of his perverted thoughts, causing him to receive the nickname the 'Pervert Prince'.As a child, he had given up his memories for the Tsutsukakushi sisters. Though over time, he becomes closer to Tsukiko, Azusa, and Tsukushi.
