Hentai Ouji to Warawanai Neko

The largest pervert in school, Yto Yokodera, is a second-year high school student. His inability to express his true emotions is his problem. One day, his equally perverse best friend has a total transformation and rids himself of all of his "impure ideas," a feat he credits to the strength of the "Stony Cat" statue. As per the reports, one can wish to wish away a personality attribute from themselves that they no longer wish to have by making a wish upon the statue and making a sacrifice to it. But by doing this, the undesirable quality will be taken away and given to someone who actually needs it. Tsukiko Tsutsukakushi, a girl, shows up while Yto is making his offering to the statue and expresses her want to be able to act more maturely and control her emotions. When they both make a wish on the stony cat, they are surprised to find that the next day at school, Yto is unable to speak a single lie and Tsukiko is unable to exhibit any sort of emotion. They cooperate to try to identify who has received their trait that was taken away in order to get it back after understanding that they do not like the change that has occurred. They come across Azusa Azuki, a lovely second-year student who has recently transferred to their institution. She is frequently confessed to by numerous lads at school, but she lacks friends and is constantly by herself. When Yto learns that Azusa is the one who inherited his undesirable personality feature, he makes an effort to get it back. They grow fond of one another while they work to regain the undesirable quality.
