After World War III, mechanical lifeforms built specifically for battle, Tactical Dolls, has been in common use. One day, the T-Dolls of the weapon manufacturing company, Sangvis Ferri, suddenly launched a revolt against humanity. The PMC Griffin & Kryuger deployed the elite T-Dolls team, AR Team in a top-secret mission to infiltrate Sangvis territory. However, they ended up meeting Sangvis's elite T-Doll, Agent...

The AR Team managed to defeat Sangvis Ferri's Agent, but G&K's support unit was wiped out, and the team has to disperse to allow M4A1 to reach G&K HQ. Meanwhile, the newly appointed commander in G&K's forward base, Gentiane, has finished her first mission and is getting to know the Dolls over there. However, a new assassin from SF, Scarecrow, has appeared, signaling the end of their peaceful times...

After the battle with Scarecrow, Gentiane is tasked with the mission to search for the missing M4A1. However, Kalina and the Dolls noticed that Gentiane seemed a bit down after the incident with Scarecrow. After a while, Gentiane noticed that M4A1 was indeed at the places where Gentiane sent her search team to, yet somehow M4A1 never made any contact with them. As Gentiane figures out why M4A1 acted this way, another Sangvis Ringleader showed up.

After getting rescued by Gentiane's squad, M4A1 managed to contact the other members of the AR Team. After requesting Gentiane's help, they head out to rescue AR-15 and SOP II first. M4A1 and Gentiane's squad has to clear out the enemies in the area first, but M4 has reservations about Gentiane's roundabout tactics. After clearing the area, M4 is reunited with SOP II, but AR-15 is nowhere in sight ....

Despite previously saying otherwise, Gentiane launched a mission to rescue AR-15 from Hunter, and send M4A1 and other Dolls to scout Hunter's location. They then found that Hunter is inside a huge base with numerous fortification and troops. Before they could make another move, Hunter contacted the team and asked for M4 to surrender in exchange for AR-15's live. Before she could decide, an explosion erupted from the base, surprising everyone.

Gentiane deployed M4A1 and the other Dolls back at area S09 in order to draw SF's attention away from the 404 squad, a Griffin spec ops unit investigating within the area. However, hours after the operation started, there's no sign of the SF unit slowing down, which raises suspicion on what's going on at the SF side. Meanwhile, during the mission, M4 was contacted by M16, informing that she is all right.

Gentiane led her teams on an assault to SF controlled nodes. Surprisingly, the SF Ringleader of the area, Intruder, taunted Gentiane on open channel, before revealing that they fell before her trap. In the midst of this stress-inducing situation, Helian informed Gentiane of the Ringleader's location, to which Gentiane sent M4A1 and her echelon right away.

The AR Team heads out to recover data after M4A1 noticed that there are changes in their battle log. After finding the data and handing it to Gentiane, she noticed that this data indicates that there might be a commander leading the AR Team back during their mission at safehouse #3, but for some reason, the AR Team's memories of said commander seem to have been erased...

The AR Team successfully took out Sangvis Ferri’s control node and stopped the attack on Griffin’s secret base. However, upon their return to said base, AR-15 is immediately arrested on suspicion of leaking information to Sangvis Ferri, willingly or not. While AR-15 is being interrogated and checked for virus, Gentiane and the other commanders, along with the AR Team, has started another mission in order to take pursuit of Destroyer ...

Despite the situation regarding AR-15, the AR Team kept pursuit of the escaping Destroyer. M4A1 who is restless made the rash decision to chase Destroyer too far ahead, and was lured into SF’s Jupiter cannon bombardment range. Kryuger, who knows the real value of the AR Team, ordered all the Doll Commanders to make sure the AR Team pulls back safely, even if it means sacrificing other Dolls...

The search for AR-15 continues, and Helian lent Squad Negev to Gentiane to help on her search. On their way of tracking AR-15, Squad Negev's comms is suddenly jammed and they are surrounded by a massive amount of SF units led by a new Ringleader, Alchemist. The AR Team wishes to rescue Squad Negev, but Gentiane is hesitant on sending them to a dangerous battle after knowing that their neural cloud couldn't be backed up.

M4A1 was contacted by Sangvis Ferri’s Mastermind through AR-15 who is infected with Parapluie, who seemed to want something from M4. After failing to get the answer she wanted, she ordered AR-15 to take M4 to her, but AR-15 refused. Because of that, Mastermind sent a huge amount of SF forces, including Alchemist, to hunt them down along with the other Griffin Dolls in the area. ...
