Character Info
Design
Designed by the same artist as most of the AR Squadron, RO retains the same long black hair with a different colour strand on the side fringe. Items such as a name tag, hooded coat and speaker phone can be found in her possession, possibly to represent her service in the law enforcement units or anti drug departments of investigative agencies.
She is also one of the heterochrome T-dolls in the game, other examples of heterochromic T-dolls are HG Mk23Mk23Mk23 and HG SPP-1SPP-1SPP-1.
Personality
Lawful Good alignment character, RO emits a strong aura of justice around her, much of her speech and quotes resembles an officer of the law. Logical and rational thought processes renders RO as one of the few "normal" T-dolls in the entire game.
Being a T-doll of justice, RO enjoys collecting law enforcement films made before WW3, such as films of anti-crime and detective genre, but dislikes mafia films. Player base would suggest that another one of RO's part time hobby would include singing, and she might be really bad at it. It is also notable that in her dorm chibi, RO speaks to other T-doll through a speaker phone.
In-game
Combining her own evasion buffs with an enemy damage debuff in her short initial cooldown skill, she is one of or possibly the strongest tanking SMG units in the game when it comes to extended combat session tanking. Offers high accuracy tile buff to a wide area, RO sits comfortably in the middle of many AR/SMG echelon formations.
Story Involvement
RO as a character is part of the AR Squadron and has major interactions with the story and events of Girls Frontline.

Palette Squadron and File 36
RO's first story appearance. She arrived at G&K to complete an assigned mission while leading a makeshift squadron going by the name Palette Squadron.
RO was assigned to G&K with the mission of recovering "File 36". Three other T-dolls consisting of HG Type 92Type 92Type 92, MG AAT-52AAT-52AAT-52 and SMG Sten MkIISten MkIISten MkII were assembled together just for this mission. According to Type 92, her temporary adjutant, they are all misfits within G&K, hence the name Palette fits them quite well, with all their colourful personalities. RO's command module was meant to be tested and fine-tuned by leading this "Bad Company". She also gained quite a lot of experience and friendship while commanding this band of misfits.
The operation began when 92 fetched an updated location information of File 36. A field operative T-doll named AAT-52 had it, but she was also trapped in the city, making the initial stage a rescue operation for AAT. After rescuing AAT, she revealed the location of File 36 to be under the possession of an unidentified human within the city. Arriving at the location of the safe house AAT provided, however, the human was missing along with all evidence.
The human was then found by Sten MkII. Over radio communication, Sten reported that the human locked himself in an office room refusing to come out. Sten also reported a large Ferri infrastructure being established near the city outskirts. RO quickly relocated the unit towards Sten's location. Upon arriving at the office building, the large Ferri infrastructure is confirmed to be a Jupiter cannon. Sangvis Ferri begin to bombard the city. A Jupiter cannon scored a direct hit on the office building the human hid himself in. With the human critically wounded and dragged outside by Sten, 92 and AAT promised to perform first aid on him while Sten re-entered the building to search for the file.
Before Sten could secure the document, another wave of artillery strikes hit and RO lost contact with all of her team members on the field. RO panicked and fell into despair, thinking that she caused her team's deaths until HG MakarovMakarovMakarov enters the scene with updated Intel. Ferri might be testing their Jupiter cannon's destructive power on that city. According to Makarov, the shots appeared to be random, so the chances of RO's team's survival is high. Hearing this, RO regained some morale. She deployed Makarov into the city to rescue the other members of Palette squadron. While en-route to her location, Makarov proposed that the artillery strike might not have been random, that they might be the tricks of the Ferri's leader. Not a second later, an artillery shell landed on RO's field command post. However, all of RO's command unit was safe. They rushed back to RO's command post and, in a joint effort, they dug the unconscious RO out of the debris.
Fortunately, RO only suffered minor injuries. Makarov called an extraction team to evacuate Palette squadron out of the city. With File 36 in hand, Palette squadron's operation is accomplished, but with the city now in ruins. Palette squadron disbanded after this operation as RO was needed to replace AR ST AR-15ST AR-15ST AR-15 in the AR squadron. This short time they've had together left a deep friendship between them and RO as comrades.
Mario Princess Facility
RO's first appearance is in chapter 7, when she officially joined AR squadron.
RO officially entered the scene after the siege on AR squadron's position, the Mario Princess supervision facility in Sector S05. Persica introduced RO to the Commander while the facility siege intensified, RO states that she was developed especially for this task and requested the Commander to capture a comms relay station used by the Ferri in Sector S05 to speed up her deployment into the battlefield.
With the comms relay destroyed, Dreamer launched an attack on the supervision facility directly, claiming to kill every single T-doll present there, if the Commander divert forces to fight Dreamer, the facility itself will be left undefended. RO stated that she will infiltrate and rescue the T-dolls at the facility, while the Commander can focus on fighting Dreamer, the Commander agreed to this proposal.
Soppu asleep on RO's lap
While the G&K forces were defending outside the facility, Mastermind sneaked in the facility in attempt get close to AR M4A1M4A1M4A1. Equipped with her advanced jamming module, all the other T-dolls within the facility were unable to move, Mastermind reached M4A1, attempted at deciphering her Cloud Atlas. Failed to decipher anything, Mastermind decided to take M4A1 with her back to the Ferri HQ. RO enters the scene, with her counter counter-measures she manage to negate Mastermind's jamming, with all the other T-dolls up and operational, Dreamer being pinned down by G&K forces, Mastermind was forced to retreat from the facility.
M4A1 however was no longer combat capable, after the attempt Atlas decryption, she was left in a state of delusion, constantly mumbling to herself. Tidying up the battlefield, the Commander finally met RO face to face in the facility's garden, with AR M4 SOPMOD IIM4 SOPMOD IIM4 SOPMOD II sleeping on her lap. RO formally introduced herself to the Commander, she is here at the request of Persica to assist the Commander, but she wishes to keep that a secret from the HQ. She also inform the Commander that Persica will do something about M4A1's current condition, in the meantime, she will take over the Command for AR squadron.
Hunt for Dreamer
An immediate follow up after chapter 7's story, where RO and AR squadron fought Dreamer in Sector S05.
RO had solid Intel on location of Dreamer within S05, she is under the order to annihilate Dreamer, AR squadron she led is performing this task. Palette squadron members are here to help with this task, the operation began with each member of the AR squad meeting a member of the Palette squad on the field, AR M16A1M16A1M16A1 were to meet AAT, SOP II were to meet Sten and RO were to meet 92. Upon meeting of the Palette squad members, Ferri forces commenced bombardment of Sector S05 with their Jupiter cannon infrastructures, SOP II and Sten's location suffered a direct hit.
After confirming Intel, M16 departed to SOP's location while AAT relocated to meet RO. Upon meeting with Sten, she reported that under Dreamer's provocations SOP has gone berserk and ran after Dreamer, M16 went after SOP with Makarov who just entered the scene. Sten's next task from RO was hacking a Ferri Jupiter cannon, to disrupt further bombardments from Dreamer. Dreamer was never present in Sector S05, all the present Dreamer units are her dummy-links, she enraged SOP, forced M16 to go after the furious SOP and attempted to destroy them both with a well placed Jupiter shot, fortunately through the hacking of the cannons, the shot did not cause ideal level of damage, the two survived.
The evacuation route was however block directly by Dreamer, with the help of Commander's forces, both AR squadron and Palette squadron extracted without further casualties. To celebrate the destruction of all of Dreamer's dummies in Sector S05, RO had a few drinks with M16 in the bar, they had a long chat about AR squadron's past, about M4A1, about AR-15 and about the next step of their vengeance.
Arctic Warfare

Annihilation of Mastermind
Immediately after being rescued from S02, AR squadron received a new order, a joint operation with SOCOM and the annihilation of Mastermind.
9mm SMG developed with M16A2 as the basis, actually manage to maintain a fair share of the market, even in the era dominated by MP5. Great balance and performance, but my proudest achievement was my service in policing agencies and special combat units, took part in all kinds of anti-crime operations, it was my honour and glory.
I believe you have your reasons to why I was the one being chosen. Looks like you finally accepted me and my beliefs, but... Please try not to get too close, everyone... They're all watching us.
A Girls Frontline 4Koma artist named Xiuhui made a remark of RO's mental shock in one of her twitter posts, which unofficially suggests RO might be decreasing enemies' damage by singing into her speaker phone REALLY LOUDLY.
