Akaba

Akaba (赤羽) is one of the boys who hails from Hokuto, part of the Hokuto Three Crows led by Kazumi Sawatari. He is able to change into the Castle Hard Smash (キャッスルハードスマッシュ) at will by using the Castle Fullbottle.

History
When Hokuto Prime Minister Yoshiko Tajimi declared war on Touto, Akaba was part of the advance guard with Aoba and Kiba. Through his power as a Smash, Akaba launched a premature strike at the city. Disregarding Kiba's warning against disobeying the boss, Akaba called out to their superior who was engaged elsewhere, asking if he was finished.

Akaba and the others later tracked down Sento Kiryu and Ryuga Banjou, and transformed into their Hard Smash forms. After successfully knocking them out of their transformations, Akaba demanded that they hand over their Fullbottles, prompting Aoba and Kiba to argue with him over who should get said Fullbottles. By the time they had pulled themselves together, Sento and Ryuga had absconded.

Later, they found Sento consoling Misora Isurugi as she lamented her role in allowing evil to wage war, and told Sento to hand over his Fullbottles. This time, Sento gave them a challenge with a determination he gained from Misora, using RabbitTank Sparkling Form. However, Akaba, Aoba, and Kiba still quickly gained the upper hand, until Ryuga appeared with the Sclash Driver and transformed into Kamen Rider Cross-Z Charge. Ryuga and Sento easily defeated them, causing them to drop the Phoenix, Robot, Wolf, Smapho, Kuma, and Televi Fullbottles. Kazumi Sawatari arrived shortly after to challenge Sento and Ryuga.

Personality
Akaba is a delinquent right down to his appearance and personality. He is cruel and careless, not hesitating to attack a civilian population out of boredom. Akaba sees himself as superior to his comrades, barring his Captain.

Akaba, not unlike the rest of his team, is very petty and immature, even arguing over who would take Sento and Ryuga's Fullbottles after defeating them. He and his team were called idiots by Ryuga within minutes of meeting him.
