Monster Ops: Neutralization

The Monster Ops: Neutralization (Monster’s of a New Law (モンスターズ・オブ・ア・ニューロゥ) in the original Japanese, or MONster's New Law (モンスターズ・ニューロゥ) in the anime series), or M.O.N. for short, is a squad of monstergirls tasked with dealing with monsters who exploit the Interspecies Protection Act.

Formation
Due to a loophole in the new Extraspecies Laws prohibiting violence against non-human sub-species, the police are unable to use necessary force to arrest extraspecies lawbreakers. The M.O.N, is a special unit comprised of four monster-girls, and led by Smith, to handle such "untouchable" situations involving extraspecies lawbreakers.

They were first called in to to deal with a gang of Orcs that had taken over a Libido Dojin. Manako sniped all their guns from a distance, Doppel disguised herself as a girl from one of the Dojin to draw the Orcs' attention, Tionishia got the hostages to safety, and Zombina took the Orcs' gunfire by pretending to be wounded, then launching a surprise attack on them. After arresting the Orcs, the team came to Kimihito's house with Smith for dinner.

The M.O.N. were later assigned to apprehend Rachnera (although Doppel was annoyed she didn't have anything to do), however she escaped. Later on they tracked her down to a warehouse where Smith agreed to having transferred her to Kurusu's household.

Later on, when Kimihito was sent a death threat, M.O.N. were assigned to act as guards while Smith went on a "date" with him, however the operation failed when Miia and the rest of the girls arrived.

Attire
All members of M.O.N.(excluding Doppel and Smith) wear a flak jacket with their team name on the back.

Trivia

 * It can be inferred that after Chapter 22 Manako, Zombina, and Tionishia may have become attracted to Kimihito.
 * They have a theme song of their own in the form of the anime's ending song "Hey! Smith!" which is sung by the seiyuus for all the members.
 * Although the four girls from MON originally played a large role in the manga series, they haven't appeared or been mentioned in the main series since Chapter 52.
