Her name is Kokomi Teruhashi. She is the ultimate beautiful girl in the universe from the Japanese anime [The Disastrous Life of Saiki K.]. She is a student in Class 2-3 at PK Academy. There is no man who doesn't say 'Offu' upon seeing Teruhashi. Furthermore, Teruhashi is a person loved by God himself. With her perfect looks, slender and sexy body line, and a personality kinder than anyone else's, Kokomi Teruhashi has become the perfect beautiful girl. She is so perfect that a literal halo shines around her. Her goal is to make Saiki Kusuo—the only one who doesn't say 'Offu'—finally say it. Teruhashi has an older brother, Makoto Teruhashi (stage name Toru Mugami), who is a famous top actor. Although Teruhashi is his biological sister, Toru Mugami perversely loves her for real and absolutely hates it when Kokomi Teruhashi hangs out with other men. The person this perfect Teruhashi fell for is Kusuo Saiki, a hidden psychic who looks ordinary on the outside. However, Saiki uses his psychic powers to avoid Teruhashi... Since Saiki desires normalcy, he takes care not to get involved with the beautiful Teruhashi. She is so beautiful that a parasol will naturally find its way to her when it's hot, and a rickshaw will appear if she finds it hard to walk. Her brother worries that Teruhashi might get scouted... She once bought an item at a store for only 20 yen using discount coupons, even though the original price was 6,850 yen.
