History
At some point of his life, he joined the Japanese Imperial Demon Army. Eventually, he became part of Shinjuku Security Unit's Third Platoon and got promoted to the rank of corporal.

Story
Nagai emerges from behind an intermodal container to face the vampires that have descended from a helicopter. He calls for his platoon to prepare for battle them as the defense of Shinjuku is in full force. The Shinoa Squad joins them. After the vampires are defeated there Nagai approaches to say how they really appreciated their help, and how intense that was. Nagai shares that he is with the Shinjuku's Security Unit, the third platoon to be exact. Assuming that they are the Vampire Extermination Unit, Nagai is impressed to hear from Shinoa Hīragi that they are part of the Moon Demon Company. He guesses that their luck has not run out yet, and he orders a pair of soldiers to arrange a transport for them. They regroup at army tents where supplies and numerous soldiers in the medical tent are kept. Nagai informs Shinoa Squad that the vampires got through the west defensive barrier shortly before their arrival. They have a counterattack squad holding them off right now but he is unsure of how long they will last. Agreeing with the tactical situation being much worse than expecting, Nagai states it has been a nightmare from the start. Asking whether Shinoa's group could head west to reinforce their defenses, he guesses that Yūichirō Hyakuya is right when he is assured that is why they are here. The pair of soldiers return and state that the vehicle is prepped and ready to go. Nagai replies he will take Shinoa Squad as close as he can to the western defense and he advises them to remain on high alert. Later he transports Shinoa Squad in a cargo truck and informs them they should be at the defensive line in the next fifteen minutes. Things might get a little bumpy and he drives as the squad discuss the cursed gear stimulant. Missiles from a helicopter suddenly fire at their vehicle and cause it to slide then flip over. Whilst Shinoa squad are hurled out the vehicle yet escape to the ground outside, Nagai is unconscious in the drover's seat. He is pulled through the smashed front window by Yu with Shinoa's help and defended from the helicopter machine gun fire by Mitsuba Sangū and Shihō Kimizuki. After Yoichi Saotome uses his cursed gear to shoot the helicopter, it explodes but not before launching three more missiles. Nagai has been carried away before the truck he was in is destroyed. The missiles destroy the ground beneath Shinoa and Yu, and he falls with them into the subway below. Noted as being banged up pretty badly, Nagai is meant to be taken to the temporary shelter above ground where his wounds can be treated by medics. Receiving help from Yu and Shinoa means they will meet Kimizuki, Yoichi and Mitsuba at the defensive line later. He is carried by Yu through the tunnel.

Once they get above ground, Nagai had been taken to a medical tent, and Shinoa says he will be fine there with the doctor stating he will recover.
