Akaba

"Boss... thank you... for everything," - Akaba's last words, before handing Kazumi Sawatari his dog tag.

Akaba  (赤羽 Akaba) is one of the minor antagonists in Kamen Rider Build. He was born as Masaru Ooyama (大山勝 Ōyama Masaru, but after being experimented on and joining Kazumi Sawatari, he was given the name Akaba, thinking that Kazumi would actually refer him as so. Later in the series, Akaba becomes part of Sento's team, after Kazumi lost the proxy battle. He uses the Castle Fullbottle to transform into Castle Hard Smash. Later on in the series, he gets upgraded into Castle Hazard Smash. He is portrayed by Eishin.

History

In The Weaponry Hero, Akaba and the Hokuto crows were shown spying at the Kamen Rider, and Cross Z Dragon.

In The Idol Awakens, Akaba was discussing to Kazumi about burying the dog tags of his lost friends at the Sky Road, which Kazumi agreed too. Suddenly, Kazumi needed to go out and told Akaba to stay put and contact him if anything wrong happens. He agreed. After some time of him leaving, a man named Rogue broke in and asked to hand over the Pandora's Box.

Of course he wouldn't allow it!

He started fighting, but it was futile, so he informed Kazumi that he was getting attacked, and Kazumi arrived there.

Ir was a bit too late though, he was near death. Kazumi was only there to witness his death in front of his very own eyes. He was killed with the finishing attack, Crack Up Finish by Rogue. Before he vanished, he stuck out his hand with his dog tag, and gave it to Kazumi, before disappearing.

Personality

Akaba has a delinquent attitude, which can be ruthless and cruel. He can just mercilessly attack a civilian to his own liking, just because of boredom. He also can be quite immature and start a random argument.

But despite these negative personalities, he is also a caring friend. He looks out for one another of his friends. After the death of his friend, Aoba, he became violent and hostile, rampaging more and being stubborn.

But however, his stupidity can also lead to his death, as Kazumi has mentioned many times. He likes to define them as idiots.

Transformations

Akaba will take the Castle Fullbottle, and shake it a bit before placing it at his hand. Later, after his Hazard level was notched by the Hazard Trigger, every time he transforms he will naturally transform into Castle Hazard Smash.
