Kiba

Kiba (黄羽), born Syoukichi Mihara (三原 昌吉), was one of the boys who hailed from Hokuto, part of the Hokuto Three Crows led by Kazumi Sawatari. He was able to change into the Owl Hard Smash (オウルハードスマッシュ) using the Fukurou Fullbottle. After being administered by the Hazard Trigger, he became Owl Hazard Smash (オウルハザードスマッシュ)

History
When Hokuto Prime Minister Yoshiko Tajimi declared war on Touto, Kiba was part of the advance guard with Aoba and Akaba. Watching a live stream of lesser Smash being defeated by Kamen Rider Build, Kiba noted their limitations. He chided Akaba's use of his Smash power to attack the city prematurely, warning him not to cross the boss.

Kiba 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.
