Kouhei Hayami

Kouhei Hayami is the current principal of Amanogawa High School after Mituaki Gamo became the school board chairman. He is also the Libra Zodiarts, a Horoscope with mysterious abilities.

Personality
Hayami is an attractive and charming young man that most of the students, parents, and faculty of AGHS fall for (save Chuta Ohsugi). He however, has ulterior motives, much like fellow Horoscope Sarina Sonada. After she is defeated by Kamen Rider Fourze, Hayami takes over her duties.

Abilities
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 mothers, who have heard things about the Zodiarts attacks.

As the Libra Zodiarts, Hayami wields a staff named Dike as his weapon to create illusions, fool his targets, and can copy Kamen Rider Fouze's powers to assume a doppelganger form known as False Kamen Rider Fourze.

Etymology
His given name Kōhei (公平) is also the Japanese word for "fairness", "impartial", and "justice", referencing his Zodiarts alter-ego.

Trivia
Kouhei is played by Kousei Amano, who previously played Kamen Rider Garren in Kamen Rider Blade.
