Kouhei Hayami was the principal of Amanogawa High School. He was also the first Libra Zodiarts, a Horoscope with mystifying abilities.
Hayami is an attractive and charming man that most of the students, parents, and faculty of AGHS fall for (save for Chuta Ohsugi). He however, has ulterior motives, much like fellow Horoscope Sarina Sonada. After she is defeated by Kamen Rider Fourze, Hayami takes over (albeit reluctantly) her duties as dispenser of Zodiarts Switches. True to the nature of his Zodiarts, which is based on a star sign that takes the form of a scale, he has a habit of using terms related to weight like "light" and "heavy" when talking to others.

- Hayami has a Ph.D in physics, which puts him in a good position to be the principal. He is able to calm an entire crowd of worried and protective mothers, who have heard things about the Zodiarts attacks.
- As the Libra Zodiarts, Hayami wields a khakkara called the Dike as his weapon to create illusions, fool his targets, and can copy Kamen Rider Fourze's powers to assume a doppelganger form known as "Fake Kamen Rider Fourze Base States", as well as brainwashing the victim, such as the Perseus Zodiarts. He demonstrated his illusion abilities by making an unconscious Sonada have the appearance of Gentaro Kisaragi to throw off Kamen Rider Fourze (who is Gentaro). The khakkara can also be used, even from an incredible distance away from Dike, as he destroyed the last alter in Kyoto while he was in space, simply by channeling his power through the khakkara.
- After being defeated by Fourze, Gamou decided he was useless, and it was time to send him to the Dark Nebula. Hayami was so desperate to not be sent to the Dark Nebula, that he manifested his Supernova ability, which is the Eye of Laplace, which allows him to see who has the potential to be a Horoscope. Gamou, upon Hayami learning him being the Sagittarius Zodiarts, delays his trip to the Dark Nebula, letting him stay on Earth to find other potential Horoscopes' members.
