Kenta Imai (今井 健太, Imai Kenta), more commonly known as Kyu Saijo (西城 究, Saijō Kyū) is a writer and the network researcher of the Special Investigation Unit.

History[]

Kenta Imai, well known by his pen name Kyu Saijo, is a digital expert and he is talented at information-gathering. He is also is a popular writer in the otaku community having written a bestselling novel, Hurray! Internet Life. Kyu was hired as the Special Investigation Unit's network researcher, however his approach towards cases is sometimes frowned upon by the whole unit.

Kyu is noted to be a fan of the anime, Murmur Mansion and mostly assists the team with clues regarding the culprit while trying to get information on the mysterious Kamen Rider. Despite his overwhelming passion with his occult hobbies, he remained a valuable asset to the Special Investigation Unit as he was able to provide Shinnosuke and Kiriko clues to lead them in their cases.

One night, he came across Roidmude 072 and begged to watch the final episode of Murmur Mansion before the Roidmude kills him. While the Roidmude decided to honor his final wish, he ended up not going through his mission after connecting with Kyu. Kyu let 072 live with him at his place and even letting the Roidmude take his place in the Special Investigation Unit on certain occasions. The copy was killed by Medic after he was unmasked. Kyu was deeply saddened by 072's death after he was told that his friend went berserk and killed by Kamen Rider Drive. In reality, 072 requested Drive to lie about his death as it would deeply sadden Kyu. Despite 072's loss, Kyu found an alternative way to detect Roidmudes by tracing their data patterns.

Otta and Kyu screaming

Otta and Kyu find out Drive's secret identity.

During the plight of the Sword Roidmude, Kyu was sent by Shinnosuke to keep an eye on Kiriko Shijima because of her suspicious behavior at the time. He tailed Kiriko in the woods where he discovered her with Chase. While he was frieghtened by Chase, he understood Kiriko that not all Roidmudes were not evil as he could relate. Kyu and Lt. Otta would finally learn Shinnosuke Tomari was Kamen Rider Drive after seeing him transform to save Akira Hayase. After the fight ended, they also learn Kiriko's brother Go being Kamen Rider Mach. Kyu and Otta were brought to the Drive Pit for the first time where the Special Investigation Unit are now offfically part of the Kamen Riders' activities, with Kyu further providing him with clues regarding later Roidmude related incidents.

Eventually, the Special Investigation Unit have accomplished their mission of shutting down the 108 Roidmudes and ending Tenjuro Banno's reign of terror. With their mission complete, Krim locked himself and all Core Driviar equipments beneath the wrecked Drive Pit. After several parting words, Mr. Belt prepares the lockdown and all of the Unit members saluted for him. Following this, Kyu went on to become a popular network researcher and author once more. His latest novel, Mechanical Friendship became a best seller.
