Haru Kusao

is a meek new first-year student at Amanogawa High School who receives a Zodiarts Switch from Libra and becomes the . The reason why he wanted the Switch was to protect his (for a long time, only) friend Ran.
She had long sworn to protect him, after an incident where upperclassmen at their previous school threw Haru's friendship charm with Ran's name on it into the pool and teased him, but she stood up for him and retrieved the charm, thus gaining a disdain for upperclassmen. However he had gotten a high off the switch, and still saw Ran trying to protect him (as both himself and the Musca Zodiarts), leading to an increasingly unstable mental state.
However, his power to convert his body into a swarm of flies was negated when Fourze used the power of the Net Switch onto Musca, forcing the Zodiarts to stay solid while Fourze assumed Magnetstates. However, Kengo warned that if Haru's Zodiarts form was destroyed while he was mentally unstable, he would remain that way. Just then, Ran yelled to Haru an apology for trying to protect him when he didn't want protecting. Haru's heart was reopened, and he asked Gentaro to send him back to his body, and was blasted away by a Super Electromagnetic Bomber.
Later, after returning to his body, Haru is given provisional membership alongside Ran while recuperating from his injuries in the hospital. However, Haru was used by Leo to bring out Ran, who was the last Horoscopes, Pisces. By the end of the series, Haru and Ran become official members of the renamed Space Kamen Rider Club.

==Notes==
* Haru being the Musca Zodiarts may be reflected in his name, which is one letter removal away from becoming the vulgar word "Kuso", which can be translated into "crap" in English.
* Haru is the first character to be revealed that one of the Members of Horoscopes is from school faculty.
