Asano further stated that Kogami was the easiest character to draw due to his tendency to express an angered reaction. Due to him and Tsunemori being the lead characters, Asano felt like he could care about them. The character has been compared with Charles Marlow in Joseph Conrad's 1899 novel, "Heart of Darkness". Like Marlow, Kogami's obsessive hunt draws him close to his prey. After Kogami kills Makishima (and abandons his ideals), he decides to leave society and Tsunemori. Since the series was "anti-"moe"", the developers avoided having Tsunemori take off her clothes. Instead, Kogami got undressed instead, providing fan service to the female audience. The staff's main idea was Akane finding the renegade Kogami was influenced by the original video animation series "" and the Western films "Apocalypse Now" and "Saving Private Ryan". Akane's search for Kogami was influenced by these films because the staff believed this scenarios would appeal to both genders; Shiotani also wanted adult viewers to be able to enjoy it. The non-romantic relationship between Akane and Kogami was viewed as appealing by the staff because of the trust they have in each other. The duo was stated to resemble Sumire Onda and Shunsaku Aoshima, the lead characters of the Japanese police comedy-drama "Bayside Shakedown". Shinya Kogami is voiced in Japanese by Tomokazu Seki who was cast by Katsuyuki Motohiro during auditions for the series. Seki had little knowledge about the series's premise. He was also cast for the role of Nobuchika Ginoza, but ended with Kogami. Seki enjoyed the role and anime. He liked the character and believed that he would fit in the second season as a protagonist strong enough to defeat new antagonist Kirito Kamui. However, Kogami only appears in the second series as Akane's hallucination when she thinks about how to deal with Kamui. Kogami was happy with the impact his character had on the inspector. Because production of the 2015 film did not begin until late in the second anime's production, cast members were concerned that Kogami had been killed off-screen and when the film was announced, were relieved by the character's survival after he disappeared in the first series. Shiotani decided to have the foreigners speak English, in contrast with other films in which they typically speak Japanese.
