Plot

Yōto Yokodera, a second-year high school student notorious for being the school's biggest pervert, finds it difficult to convey his genuine feelings. His best friend undergoes a sudden transformation after making a wish on the "Stony Cat" statue, an artifact that grants wishes by transferring unwanted personality traits to others. Both Yōto and Tsukiko Tsutsukakushi make wishes—Tsukiko desires to be more mature and less emotional. The following day, Yōto loses the ability to lie, while Tsukiko becomes incapable of displaying any emotions.

Dissatisfied with these unintended consequences, they set out to recover their lost characteristics. Their search leads them to Azusa Azuki, a popular yet isolated transfer student who has inherited Yōto’s discarded trait. As Yōto attempts to reclaim his original disposition, he and Azusa begin to develop romantic feelings toward each other.

Main characters

Yōto Yokodera (voiced by Yuki Kaji): Yōto is the protagonist and a second-year high school student. Known secretly as a major pervert, his difficulty in expressing himself often causes misunderstandings. After wishing on the Stony Cat to remove his "façade," he loses his ability to lie and starts voicing all his thoughts candidly, earning the nickname "Pervert Prince." He later endeavors to retrieve this façade from Azusa. Throughout the story, he builds closer relationships with Tsukiko, Azusa, and Tsukushi. He also sacrificed memories involving Tsukasa years earlier for the Tsutsukakushi sisters and gradually develops feelings for Tsukiko.

Tsukiko Tsutsukakushi (voiced by Yui Ogura): A first-year student who wished upon the Stony Cat statue to become more mature and emotionally restrained. Instead, she ends up unable to express her feelings outwardly. Despite Yōto’s flaws, she grows fond of him and maintains a diary to assist him with his weak long-term memory.

Azusa Azuki (voiced by Kaori Ishihara): Azusa is a second-year student who inherits Yōto’s unwanted blunt honesty trait. Although she appears affluent and popular, she lives modestly and holds several part-time jobs. Having been bullied at her previous school, she struggles with trust issues. After Yōto regains his façade, she begins to open up and develops romantic feelings for him. She also reconciles with former friends to rebuild her support network.

Tsukushi Tsutsukakushi (voiced by Yukari Tamura): Tsukiko’s older sister and president of the track and field club, known as the "Steel King." She admires Yōto but harbors possessive love toward her sister. She believes Yōto’s fabricated tale about having a younger twin brother and envisions a polygamous marriage involving both sisters.

Emi (Emanuela Pollarola) (voiced by Aimi): A young Italian girl connected to Yōto through prior encounters. Due to her wish on the Stony Cat, she temporarily assumes the role of Ponta’s sister returning from Italy. Similar to Azusa, Emi speaks using unusual analogies. Her father maintains connections with Tsukiko’s family.

Additional Characters

: Mai serves as the vice president of the athletics club and holds Tsukushi in high regard while vying against Yōto for the club’s presidency. Her aloof attitude creates distance between her and others, yet she eventually establishes a non-romantic friendship with Yōto. She shares a childhood bond with Azusa.

and: (Morii), Aya Suzaki (Moriya); Morii and Moriya are friends of Azusa from junior high who initially teased her but later sought to build a friendship. They mistakenly assume that Yōto and Azusa are romantically involved.

: Tsukasa, mother to Tsukiko and Tsukushi, passed away at a young age due to complications from an infection. Following her husband’s death, she sent her daughters to Italy because of her declining health, which caused strains within the family. She lovingly crafted clothing for her daughters and cared for Yōto before reuniting with her children shortly before her passing.

: Azusa’s gentle mother has a particular affection for turtles.

: The Stony Cat, venerated by the Tsutsukakushi family, possesses the ability to grant wishes and subsequently reverse them. It can also inhabit living beings, demonstrated through Azusa and Ponta’s rabbit. The entity communicates using a female voice.
