|Shinnosuke Tsuji||Sumiharu Inukai|
Their battle uniform is a three-piece suit. The unit's emblem is located at the tip of the necktie, which is only visible in Inukai's case since he doesn't wear a vest.
Ninomiya Unit was formerly in A-rank and part of the Expedition Force. However, due to Hatohara's unwillingness to shoot people, they were removed from the force. Afterwards, they were demoted to B-rank, as punishment, when Hatohara broke the rules by giving Triggers to citizens. Like all other B-rank Units, Ninomiya Unit was forbidden from participating during the Second Large-Scale Invasion unless all its members were present.
Ninomiya Unit is pitted against Tamakoma Second, Kageura Unit, and Azuma Unit in a rank battle. Ninomiya orders his teammates to hunt down Tamakoma Second. Inukai engages in a battle with Osamu, where he easily has the upper hand, but he is ambushed by Okudera and Koarai, losing an arm in the process. At the same time, Tsuji intercepts Yūma as he tries to help out Osamu, who has been trapped by Inukai. Kageura appears and fights Yūma, allowing Tsuji to support Inukai. Inukai continues to fight his two adversaries until Chika fires at them. Due to the shot being too slow, he easily blocks it, and pursues Chika. Yūma attempts to help Chika, but Tsuji blocks him. Inukai is shot by Ema, and is defeated by Kageura. Ninomiya manages to find Ema, and notes that he was being partial to Tamakoma Second. Ema responds that he simply despised Ninomiya Unit. Ninomiya proceeds to take him out. After, Ninomiya saves Kitazoe from Azuma's shot so that he can defeat Kitazoe himself, which he does. Tsuji engages in a battle with the Azuma Unit Attackers and Yūma, where he is eventually shot by Azuma and forced to Bail Out. Yūma and Kageura begin their fight, but Ninomiya intervenes, taking out Yūma. With Okudera and Koarai gone as well, only the captains of the teams excluding Tamakoma Second remain. They do not attack each other and run a Time Out, where Ninomiya Unit is declared the victor due to having the most points from kills.
During the Galopoula Invasion, they act as a backup force.
