Shoichi Ashikawa (芦河 ショウイチ Ashikawa Shōichi) is the resident Kamen Rider of the World of Agito in Kamen Rider Decade.


Kamen Rider Decade

World of Agito

He is a young man who supports the police, originally the user of the G3-System that was designed to fight the Gurongi. However, he mysteriously metamorphed into Kamen Rider Exceed Gills, a larval form of Agito. Hunted by the Lords for his incomplete power, Shouichi left the G3 unit without explaining his reasons, the isolation he placed on himself making him antisocial. However, the real reason is actually because he doesn't want his presence endangering Toko. The pain of the changes inside his body worsen whenever he senses the presence of nearby Lords attacking humans.

Possessing a year-old letter for him from Toko, Tsukasa and Natsumi arrive to his long dilapidated home to give him his letter, only for them to be followed by a Formica Pedes. Amazed at Decade's power, he rips the letter Tsukasa gives him and tells him to stay away from him as they are nearly killed by an attack from the Buffalo Lord Taurus Ballista. After reading the letter, Tsukasa finds Shouichi and offers to protect him from the Lords. This however, enrages Shouichi as he becomes Gills with Tsukasa restraining him before he runs off to where a pair of Pedes are fighting Yusuke and Diend.

After killing the monsters, Gills is targeted by Diend until Decade arrives to protect him. However, Gills takes the Decadriver as he runs off when Ballista himself appears with his Ant Lord minions. Though he refuses Tsukasa's aid, it takes Yusuke's interference to help Shouichi realize Toko knew why he ran off and loves him enough to protect him by creating the G3-X Suit. This revelation allows Shouichi to complete his evolution into Agito, supporting Decade and G3-X in defeating the Unknown. Soon after, Shouichi returns to the police force to support them as Agito. Reunion: Project Agito Awakening: Tornado of Souls

When Tsukasa goes into the World of the Rider War, the only "Rider Worlds" remaining are of Blade's, Kiva's and Hibiki's. It is revealed that Agito's world has vanished like the other worlds.

Movie Wars 2010

Shouichi as he appears in Movie War 2010.

During Movie War 2010 events, he is revived after Decade's death and helps revive Decade. He later appears to help in the final battle with Super Shocker, transforming into Shining Form as a result of Decade's K-Touch and later into his Agito Tornador form with the All Rider Final Form Ride Card to fight the Super Crisis Fortress.

Later appearances

Movie War 2010 currently remains the last appearance of Shoichi Ashikawa. The Agito, G3, and Gills that appears in OOO, Den-O, All Riders: Let's Go Kamen Riders and Kamen Rider × Super Sentai: Super Hero Taisen is the original Agito, Shoichi Tsugami, the main G3 user, Makoto Hikawa and the original Gills, Ryo Ashihara

Rider Powers

Shouichi also possesses some of the same equipment used within the original Agito, such as the Altering (オルタリング Oruta Ringu) transformation belt, which holds the "Power of Agito" that serves as the source of his power. Kamen Rider Decade's Final Form Ride allows him as Agito to change into Agito Tornador (アギトトルネイダー Agito Toruneidā), a hoverboard similar to the Machine Tornador in Slider Mode.

Before he assumed the title Agito, he previously assumed the title Kamen Rider Exceed Gills (on his first appearance) and Kamen Rider G3 (as shown in Kamen Rider Decade episode 13)

The Generation-3 System was developed by the Tokyo Metropolitan Police Department's Squad Against Unidentified Lifeforms division. SAUL had received funding from the city government to develop a reinforced exo-suit to combat the Gurongi, which were known to the police as Unindetified Lifeforms. Their design was based on Kuuga, who was thought to be the fourth Unidentified Lifeform to appear. However, because the Gurongi were eliminated before its completion, research on the project was postponed indefinitely. By this time, the data acquired from the first two phases of the project had been implemented into the Generation-3 System, which was entering its final phase of development and ready for deployment. With the emergence of the Lords, the police's G3 unit was commissioned to contend with the threat.

Despite using advanced technology, G3 is vastly outclassed by the Lords and those that possess the power of Agito.

G3 is equipped with conventional ballistic weapons. His primary armament is the GM-01 Scorpion, which is holstered on his right hip. The Scorpion can be augmented with the GG-02 Salamander grenade launcher, which serves as G3's main method of destroying Lords. For close combat, he can equip the GS-03 Destroyer on his left arm. The Guardacceler, which is used to access the Guard Chaser or can function as a backup weapon, is stored on the left thigh.

Behind the scenes


Shoichi Ashikawa is portrayed by So Yamanaka (山中 聡 Yamanaka Sō), previously Kamen Rider Kirameki in Kamen Rider Hibiki & The Seven Senki and who would later portray Yosuke SakuradaIcon-crosswiki.png in Tokumei Sentai Go-BustersIcon-crosswiki.png. As Kamen Rider G3, Kamen Rider Exceed Gills, and Kamen Rider Agito, his suit actor is Jun Watanabe (渡辺 淳 Watanabe Jun).


  • Shoichi Ashikawa (芦河 ショウイチ Ashikawa Shōichi) is a composite of the three main characters in the Kamen Rider Agito series, with his name being a portmanteau of all three characters' names: Shouichi Tsugami (津上 翔一 Tsugami Shōichi) (Agito), Ryō Ashihara (葦原 涼 Ashihara Ryō) (Gills) and Makoto Hikawa (氷川誠 Hikawa Makoto) (G3).
    • This is played further as he donned the G3 suit and assumed the form of Exceed Gills before becoming Agito.


  • Ashikawa Shoichi is notably the only A.R World Rider to be based on 3 Kamen Riders.
  • Although he appears as Exceed Gills in the TV show, Shouichi was only ever referred to as Gills. Although the Gills suit was planned to be used, it had been improperly stored and degraded beyond use, leaving only the Exceed Gills suit usable.
