Sou Yaguruma/Zi-O

In 2006, Sou Yaguruma (矢車 想) was Kamen Rider KickHopper (仮面ライダーキックホッパー).

In Kamen Rider Zi-O, he transforms into Another Kabuto (アナザーカブト), an Another Rider derived from Kamen Rider Kabuto Rider Form.

2006: Next Level Kabuto
1= "Stop it, Yaguruma! This isn't Kageyama! He's just a Worm who mimicking him!" "Do you think I care? After all, only a worm is willing to be my partner!"

- Yaguruma's word to protect the imitation Kageyama from Kagami.

2= "It's not like I had the power of space to begin with. All I have is the power of Hell!"

- Yaguruma to Woz, transitioning from Another Kabuto into KickHopper.



In 2019, Yaguruma receives an Anotherwatch from Heure and is turned into Another Kabuto, with a Worm who has previously mimicked his late partner Kageyama seemingly supporting him.

He first appears to stop Gatack's attempt to destroy PunchHopper, saying to Kagami that he should not harm his "brother". The two then flee the scene. Later, PunchHopper lures out Kagami into an abandoned warehouse, where Yaguruma awaits as Another Kabuto to defeat Kagami. Kagami, along with Woz, transform and take on the Hellish brothers. Kagami tries to talk some sense into Yaguruma, but to no avail, as he believes that even as a Worm, Kageyama is still the only one who cares about him, and he will protect his partner. He then leaves PunchHopper to fight with Gatack as he takes on Woz. At first, Another Kabuto is having the upper hand with ClockUp, but Woz switches into WozGinga Wakusei and proceeds to perform an area attack, rendering Another Kabuto's speed meaningless. However, when his Another Rider form breaks, Yaguruma immediately assumes his KickHopper form and uses a Rider Kick on Woz, forcing him back. Yaguruma subsequently leaves and is seen on a river in his human form, wondering who has laughed at him.

2019: The Chosen Kabuto
Yaguruma later meets Geiz, who tries to convince him that his "partner" is just a Worm. Yaguruma still maintains that Shun is still his "brother", and that he will continue to protect him. Geiz asks why someone like Yaguruma would continue to follow the mimicked Kageyama, to which he replies that if Kageyama turns into a Worm again, he will be the one to personally execute Kageyama, just like he used to do in the past. As Geiz answers a phone call about Kageyama, Yaguruma kicks him in the stomach and leaves.

Somewhere, Kagami has been taken hostage by the mimicked Kageyama. The Worm demands the Fourze and Ginga Ridewatches because he does not want Sougo and Woz to prevent the meteorite which contains more other Worms from crashing into Earth. Woz and Sougo, however, manage to free Kagami, and prepare to fight Kageyama. Just as Kagami is charging at the Worm as Gatack, Another Kabuto shows up to defend his "brother". Being outnumbered 2 to 1, Kagami is defeated by Another Kabuto and PunchHopper as the the Worm proceeds to take away the Ginga and Fourze Ridewatches.

In an abandoned warehouse, Yaguruma is seen eating noodles with his "brother". He asks Kageyama whether he actually plans on ending the world. Kageyama affirms this, but Yaguruma says that as long as they have each other, none of that matters, and that they will still keep walking the "hellish" world forever. Heure, nevertheless, does not want the world to be destroyed, and appears before the two. He freezes time and takes away the Ginga and Fourze Ridewatches with the intention of returning them to the protagonists so that they can stop the meteorite.

Some time later, on the top of a building, Another Kabuto and PunchHopper do battle with Geiz and Woz. Geiz tells Yaguruma that there's no point in fighting as the world is about to be destroyed. Yaguruma does not care, because he only sees the Earth as "hell" anyway. The four combatants use their finishing attacks and force one another out of the transformations. Geiz, once again, tries to talk some sense into Yaguruma, but to no avail, as he now only cares about the fact that Kageyama is right beside him. At that point, Kagami, Sougo and Tsukuyomi, who have just retrieved the stolen Ridewatches, enter the fray. Sougo and Woz travel into space to stop the meteorite, leaving Geiz Revive and Gatack to fight PunchHopper and KickHopper.

As KickHopper, Yaguruma is defeated by Gatack when their Rider Kicks clash. He subsequently transforms into Another Kabuto, and proceeds to overpower Gatack, forcing him out of his transformation. Kagami gets up, and suddenly the Kabuto Zecter appears from the sky and lands on his hand. He uses it to transform into Kamen Rider Kabuto and fights Another Kabuto in ClockUp. Just as Geiz Revive Shippuu defeats PunchHopper, Kabuto manages to destroy Another Kabuto with a Rider Kick.

Yaguruma, defeated, comes by the mimicked Kageyama and asks his partner to call him "brother" again. Kageyama coldly says that he has never been "Kageyama" to begin with, and that Yaguruma has never been his "brother", as he reverts to the original Worm form and turns into dust. Yaguruma, feeling disappointed, asks someone to keep laughing at him because of his delusional actions. He later leaves the scene, traveling to parts unknown.

Personality
In Kamen Rider Zi-O, his feelings towards his "partner" has proven to be an exploitable flaw. He is deliberately oblivious to the fact that the Shun Kageyama that he sees is not real, but is in fact a Worm that is simply taking advantage of him. He becomes so delusional, that he is even willing to let the Earth be destroyed, as long as he and his "partner" can still live to walk the "hellish" world. All the words of advice from the other characters, like Geiz's and Kagami's, fall on deaf ears when they try to convice him to stop letting himself be taken advantage of.

Forms
He assumes the form of Kamen Rider KickHopper. In Kamen Rider Zi-O he used Anotherwatches to become Another Kabuto.
