In the novel, a little of his history is revealed. He and Raye Penber went through academy together. The two were apparently good friends, as he was supposed to host Raye and Naomi's wedding. After Naomi's departure, he takes over her duties.

Movie
Suruga is in charge of earning the trust of L and then get his hands on the Death Note. He follows L, Maki and Near to the Blue Ship ecological group under the command of Kimiko Kujo. He is the driver of the van L is using in order to escape from members of Blue Ship that are chasing them, in which Suruga was used as the bait. He ends up fighting with a marketer because when he is running, Blue Ship is on a one-way street and ends up running over some tents with food.

Suruga talks to L about Maki, who is already infected with the virus. Then he reconsiders and say he should drop the FBI and help L. He later becomes the bait again to help L meet with Dr. Koichi Matsudo.

Later, Suruga discusses with L the plans of Kujo and Matoba. He also reveals that his true mission was to get the Death Note. He then takes L to the airport to try to stop the airplane and Kujo's plan. At the end of the incident, Suruga thanks L, feeling honored to have worked alongside him and L says the same.

At the end of the film, Suruga visits Maki who is hospitalized with the virus and gives her a teddy bear with L's voice recorded in it.

Novel
Suruga infiltrates the Kira Investigation Headquarters and runs into a man who introduces himself as Ryuzaki, much to Suruga's surprise, as he is well aware that this is the alias which the famous detective L uses. Suruga introduces himself, his name a fake, and all records of his real name altered so that L can not find out his true identity. However, when Ryuzaki stares at him, Suruga can not help but feel unnerved, wondering if Ryuzaki can see his real name. Suruga lies to Ryuzaki, saying that he came to express his gratitude to him for avenging the deaths of Raye Penber and Naomi Misora, and tells him that if there is anything he can do to help, he will gladly assist.

Suruga more or less ends up serving as L's housekeeper thereafter, serving him deserts and cleaning his room. When Maki Nikaido comes, Kimiko Kujo follows soon after. Suruga notes her attractiveness and Maki scolds him, saying that Kujo is shy and probably even older than he is.

Suruga introduces himself to Kujo, saying that he is an FBI agent. Kujo, however, tells him that she does not know what the FBI is, much to his disappointment. Kujo stays with Maki, and Suruga suggests to L that things will begin to get exciting now that a beautiful woman is staying there. Ryuzaki, however, doesn't comprehend this, unable to grasp why Kujo is "beautiful" or Suruga's attraction to her. When Suruga later finds Ryuzaki spying on Kujo and Maki, he calls him a pervert, but Ryuzaki expresses that he does not believe Kujo truly came for the reasons she stated. Suruga does not believe this, unable to picture the innocent, naive woman of having any ulterior motive.

Suruga later finds Kujo near the building's main computer, who admits that she was trying to hack into the mainframe. She reveals that she is an undercover agent with the Tokyo Police Department, Public Security Bureau, Third Foreign Affairs Division, a counter-terrorism division. She also reveals that she was aware of Ryuzaki's identity as world famous detective L. Her intentions, she explains, were two retrieve Nikaido's antidote in order to keep it out of the hands of those who plan to use the virus to commit genocide and the antidote to make sure that they lived through it. She asks Suruga what his own intentions are, and he reveals to her that he was sent to retrieve the killing instrument used by Kira so that no one else can use that kind of power ever again. Aware that he is attracted to her, Kujo uses her charm to convince Suruga that they work together.
