Shinnosuke Tomari

Shinnosuke Tomari (泊 進ノ介) is Kamen Rider Drive (仮面ライダードライブ). Shinnosuke is a rookie police officer who has a tendency to slack off. Kiriko Shijima was assigned to watch over him and assisting him in his fight against the Roimudes.

History
Six months prior to the series, during the "Global Freeze" incident, Shinnosuke and his partner Hayase were apprehending some criminals. Hayase was cornered in between a flammable generator and one of the two criminals. Panicking, Shinnosuke pulled out his gun and tried to aim at the criminal, but due to the Slowdown effect, he accidentally shot the generator, causing it to explode and in the process, causing some pipes to collapse. As he tried to save Hayase from the falling pipes, the Slowdown effect happened once again, causing him to be unable to save his partner from being crushed.

Personality
Shinnosuke is a lazy man who enjoys slacking off than working, as he tries to remember what happened six months ago without anything trying to disrupt his mind. When Shinnosuke straightens out his tie, however, that is a sign that he has become dead serious.

Types
Kamen Rider Drive's forms are called Types (タイプ). Some Shift Cars alter the suit based on a certain attribute, whereas other Shift Cars arm Drive with a certain element or weapon, by changing the tire on Drive's suit for a Tire Exchange (タイヤ交換).

As Kamen Rider Drive, his suit actor is Seiji Takaiwa (高岩 成二) who has been the suit actor for the majority of leading Heisei Kamen Riders (except Kuuga and Hibiki).

Rider No.
As the leading Rider protagonist of Kamen Rider Drive, Drive is labeled Kamen Rider #31 (仮面ライダー31号) and Heisei Rider #16 (平成ライダー16号).

As noted by producer Shinichiro Shirakura in the run-up to the release of Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai, with the 15 Showa Riders and then 15 Heisei Riders facing off being "the point in which Heisei has finally aligned with Showa and in which both are equal", Drive, as the Rider following Gaim, marks the point where "Heisei Rider history will actually surpass Showa, making it a massive turning point for the whole franchise's history".
