Hiryu Kakogawa

"I'm Hiryu Kakogawa. Sougo Tokiwa! We're fated to cross paths countless times."

- Another Zi-O introducing himself to Sougo.

Hiryu Kakogawa (加古川 飛流) is a young man who transforms into Another Zi-O (アナザージオウ), an Another Rider derived from Kamen Rider Zi-O.

Early Life
On April 24, 2009, Hiryu and his parents were amongst the passengers on a bus tour, which had included Sougo Tokiwa and his family, and Tsukuyomi. Mid-ride, the bus was hijacked by Sworz, who had held Sougo hostage. Tsukuyomi pulled out her gun and shot Sworz in order to free Sougo, but the shot ricocheted by Sworz’s fedora and knocked Hiryu unconscious. As the bus explodes in a tunnel, Sworz sends the children, including Sougo and Hiryu to a timeline where Dai-Mazines destroy the Earth. Sometimes after that, Hiryu and Sougo were hospitalized in the same room. However, Sougo was picked up by his uncle, while Hiryu had no one left. Since then, Hiryu blames Sougo for his misfortune, unaware of the whole truth behind the incident.

Confronting Zi-O
Obtaining the Zi-O Anotherwatch from Sworz, Hiryu went on a hunting spree against former Another Rider hosts to harvest their Anotherwatches and clashing paths with Zi-O, Geiz and Woz along the way. During his hunt on Hayase, Hiryu fought against all three Riders and demonstrate the ability to outmatch Woz Futurering Quiz. With Another Ghost as his final transformation, Hiryu unveiled his Another Zi-O form and engaged in a battle against Zi-O II.

After wearing himself out, he runs off to chase Hayase and steals what remains of Another Wizard's powers. He then confronts Sougo, explaining to him that the incident from 10 years ago on the bus cost him his life and his parents, blaming the girl in the white dress for the accident. Sougo realizes that nothing he says will change his mind and they both transform and fight. However, the fight is interrupted by Geiz as he transforms into Geiz Revive and soundly defeats him. Sworz appears at the last second however and saves him.

He confronts Geiz later on but is once again defeated by his new power, wondering how to become stronger when Heure arrives and has a plan to help him get stronger: taking White Woz's Kamen Rider powers. He then shows Hiryu how to infuse the Anotherwatch with unsuspecting civilians and control the Another Riders. Creating Another Ghost and Another Gaim, Hiryu sends them out to confront White Woz. As he is about to defeat his Another Riders, Hiryu uses a blank Ridewatch to absorb White Woz's powers. During this exchange, it's revealed that stealing White Woz's powers was a plan orcustrated by Black Woz to gain his powers and confront Geiz. Eventually, Hiryu and Heure create more Another Riders to do his bidding and confront Sougo. They fight for a while, but Sougo manages to get away and meet up with Geiz. Soon though, Hiryu confronts both of them and tries to kill Sougo but Geiz grabs his arm and defends him, saying that they are friends and will keep their promise. Hiryu sees little wrong with this as both of them are exhausted from using their powers so much recently and he is still at full power and has his Another Rider Army. Despite these overwhelming advantages, both Geiz and Sougo manage to overcome and defeat Hiryu.

Despite Sougo didn't clearly remember the past, Sougo decides to apologize to Hiryu and suggest him to keep on living in the present, and didn't dwell in the past forever. Hiryu finally breaks down, and the Another Zi-O watch is destroyed... only for it to return back to normal.

Personality
Hiryu is a vengeful young man who spends most of his life finding the one responsible for the deaths of his parents -- Sougo Tokiwa. Even though that he and Sougo, as children were present in the bus accident that led to the deaths of their parents; little what Hiryu knew is that someone else masterminded the bus accident that caused his parents' deaths, and is also the same person who gave him the Another Zi-O powers.
