After realizing that vocalizing his dirty thoughts is not the best thing, Youto decides to regain his lost traits by seeking out the person who received them. Unfortunately, he was not alone in praying to the cat statue, and now he must not only fix his life, but the lives of others as well. [Written by MAL Rewrite]
