The "Hentai" Prince and the Stony Cat (The HENTAI prince and the stony cat.) (2013)

The story centers on Yōto Yokodera, a high school boy known for his lecherous and perverted behavior — earning him the nickname “Hentai Prince.” Despite his reputation, he is actually kind-hearted and struggles to express his true feelings to others. He discovers a mysterious stony cat statue that grants wishes — but only in a very literal way. When Yōto wishes to stop hiding his true feelings, the cat makes him incapable of lying emotionally or suppressing his thoughts. Similarly, Tsukiko Tsutsukakushi, a quiet and reserved girl, wishes for her own mask of stoicism to disappear, revealing her inner emotions. The result: both find their innermost thoughts now uncontrollably visible to others — leading to comedic, awkward, and sometimes heartwarming situations.
