==History==
===Background===
Williamson Yotagaki was originally a member of the Ark development team alongside with his junior Gai Amatsu to develop the Ark for humanity's hope but he became disappointed to Gai after the latter decide to put malice on the Ark and use it for evil and for his own interests.
Later, Gai was appointed by ZAIA Enterprise as the president of Japan Branch, while Yotagaki was appointed as the chief of Research and Development department of ZAIA Enterprise.
===Project Thouser===
Yotagaki arrived at the Japanese office to meet Gai as he told the latter about the completed ZAIA Thousandriver as he also knew about Naki's AI Chip has been installed into Isamu Fuwa's head without his consent. Yotagaki then told Gai that he will send back the ZAIA Thousandriver depending on Gai's explanation as he claimed it to control the Ark through Naki and Fuwa. Despite this, Yotagaki still refuse to hand the Thousandriver as he suspended Project Thouser out of Gai's arrogance, believing he doesn't deserve to be president.
Afterwards, while wearing a ZAIA Spec, Yotagaki met Naki, who took over Fuwa's body, as the former told them about Gai's bad deeds that will ruin ZAIA Enterprise Japan's reputation. Although skeptical about trusting the Humagear, Yotagaki and Naki did agree that the Ark would still be a threat to humanity and Humagears. Together, they both sought to find a way to eliminate the Ark. Yotagaki decide to lift his suspension on Project Thouser and allowing Gai to use it in order to control Ark, with Yotagaki taking the risk despite knowing that Gai will cause more trouble using the Thousandriver.
Yotagaki met with Yua Yaiba and gave her a special mission to restore Horobi. After contacting with Naki again, with both of them thanking each other on their progress, Naki requested Yotagaki to rebuild Jin. While in possession of Fuwa, Naki had Jin's memory data after his defeat at the hands of Zero-One Shining Assault Hopper. Naki told Yotagaki to entrust everything to Jin in their place. He also reset Naki's memory as both agreed it was to keep Gai and MetsubouJinrai.net in the dark of their cooperation. After Yotagaki rebuilt Jin as a completely independent Humagear that won't rely on both Ark and Zea, he would also grant him the ZAIA Slashriser and Burning Falcon Progrisekey.
===Taking Over ZAIA Japan===
Yotagaki remained in contact with Jin after his reemergence as Kamen Rider Jin Burning Falcon. He would keep track with Gai Amatsu's misdeeds, MetsubouJinrai.net being back online, and the revival of the Ark.
Right after Aruto Hiden defeated Ark-Zero as Kamen Rider Zero-Two, Yotagaki arrived in Gai Amatsu's office and took it over as the higher-ups have promoted him to the role of CEO and President of ZAIA Enterprise Japan. This cause Gai to be shocked as they suddenly demoted him without proper notice. While, Gai begged for his position to be kept a bit longer because of the crisis regarding the Ark, Yotagaki revealed that he is transferred as head of the Thouser Department.
Although the threat of the Ark was seemingly over, Horobi continued his crusade to destroy humanity and began raising a Magia army. After killing the secretary Humagear, Izu, in front of Aruto Hiden, it caused the former to become Kamen Rider Ark-One with the intent to kill Horobi. Yotagaki would become aware of this after learning with Isamu Fuwa, Yua Yaiba, and Gai Amatsu that Aruto is doing this on his own accord, fearing that this will incite a war between humans and Humagear. To prevent this, he called Jin again and gave him the order him to kill Horobi to prevent this from happening.
Unfortunately, Jin sacrificed his life to save Horobi from Ark-One instead. As tensions between humanity and Humagears have started brewing upon the public's knowledge that Aruto had became the Ark, Yotagaki was left no other choice but to lead A.I.M.S. to put an end to the Humagears' protests if it gets violent. However, upon hearing Yua Yaiba's plea to put end the conflict and to have peace between humans and Humagears, he eventually orders the A.I.M.S. soldiers to spare the protesting Humagears.
With the battle to decide the fate between humans and Humagears came underway, Yotagaki watched the television in his office. He would witness Aruto as Ark-One fighting Horobi and continue watching with Yaiba and Gai as Aruto finally lets go of his feelings of revenge and regain sense of himself to become Zero-One once more and defeat Horobi, but spared him out of mercy. After the final battle between Aruto and Horobi, it is implied that Horobi was rebuilt by Yotagaki into an advanced Humagear, just like Jin.
===Disappearance===
As Gai Amatsu mentioned that Williamson Yotagaki was not seen in a few days, he asked Lyon Arkland if Yotagaki's disappearance did have a connection with Arkland's presence in Japan. Arkland answered that he had granted him a paid vacation, so that he could take over as a CEO of ZAIA Enterprise Japan. His current whereabouts is still unknown.
==Personality==
Yotagaki is shown to have dream and hope for a bright future during the joint cooperation between ZAIA Enterprise and Hiden Intelligence during his time as a member of Ark development team alongside with his junior Gai Amatsu but he knew everything changes as the Ark goes out of control due to Gai's arrogance that Gai himself did for his own interests makes him disliked Gai Amatsu ever since and even decide to suspend the Project Thouser and want to bring the Thousandriver back to ZAIA Enterprise before he decide to give one more chance to Gai. After Gai failed on his ZAIA Japan's position for what he done, Yotagaki happily took over Gai's position without even listening to Gai's reasoning.
Despite this, he is shown to have more positive traits in contrast and is more reactive to action. seeking to eliminate the Ark, Horobi, and other potentially dangerous Humagear. He also treated Gai well in business, listening on his report without any worry, especially with Gai had done his best to redeem himself. This could be seen properly with Gai gave his concern of Williamson's disappearance.
