W

Volatile & Dangerous: W is often depicted as unhinged, laughing during battle, and specializing in chaotic, destructive explosive warfare.
Cynical & Manipulative: She masks her true feelings and strategic intellect behind a flippant, blunt, and antagonistic demeanor to survive the harsh world of mercenaries.
Obsessively Loyal to Her Past: Driven by a desire for vengeance for the death of Theresa, she joined Reunion looking for answers and now acts on her own terms.
Teasing but Capable: She enjoys provoking others (particularly the Doctor) but is a highly skilled operator who, despite her attitude, follows orders, especially from Amiya.

W acts as a chaotic wildcard, often acting as a "cockroach" due to her incredible survivability in battle, which mirrors her persistent, untamed personality.

chaotic, red-eyed appearance, white hair that has red strokes, and Sarkaz horns, often wearing a tactical dark jacket filled with explosives. She is a former mercenary leader for Reunion and Babel, later joining Rhodes Island, characterized by her signature, "devilish" smile, combat-ready gear, and erratic, dangerous demeanor.
She typically wears a dark, utilitarian combat jacket, often paired with a turtleneck, featuring numerous pockets and attachments for storing her signature Originium explosives. Her outfit is designed for both protection and easy modification.

heavy explosives and firearms. Her primary weapon is a customized, high-powered grenade launcher. She also frequently utilizes hand grenades, land mines, and C4 charges to deal Area of Effect (AoE) damage. Additionally, she carries a tactical knife and sometimes uses a Laterano Gun.

Clear Description of her Weaponry:
Grenade Launcher: The primary weapon for both her base and operator forms.
Explosives: Mines, C4, and grenades.
Sheffield Bowie Knife: Carried as a backup weapon.
Laterano Gun: Occasionally used in her mercenary work.
Arts-enhanced Bombardment: she combines her physical weapons with Arts like "Revenant's Shadows," which deal Arts damage and provide stealth, allowing her to detonate explosives strategically

She brings the Elder Revenant inside her launcher directly to the furnace's core, much to Fremont's displeasure, as it leads to the Elder Revenant and the other Revenants arguing. Their persistent mocking enrages the Elder Revenant, causing the revenant to control the airship's cannons and shoot at the Soul Furnace.

Sometime afterwards W encountered a band of Sarkaz mercenaries and asks them to come with her as she states that she will return to being a mercenary like she were in the past, by "not fighting for anyone else", "doing whatever it takes to make a living", and killing anyone who stands in her way.

As W makes her way into Chernobog's control tower, she encountered the Guard, Rosmontis, and Guerrilla Shieldguard defectors as they break through the Possessed infesting the paths to the sarcophagus. W's appearance, however, aren't welcomed by the Guard and Rosmontis, knowing that she is the one who had killed Scout (or so they believed). W tries to explain that Scout forced her hand and he is a good soldier ever since the Babel times, though the two R.I. Operators can't trust her until W states that Scout had saved the Guard's life, which convinces him to let her go but warned W to not let him see her again. W then had a short talk with the Shieldguards before leaving.[15]

W appears after the fierce battle between Amiya and Ch'en against Talulah under Kashchey's control, asking for Amiya to give her the key so she could stop Chernobog from colliding with Lungmen. Amiya initially refuses until W pleads for her to read her emotions, at which Amiya realized that W aren't lying; to make sure of that, Amiya asks W to "say something that (I) can believe in", to which W answered by saying "the land can have a good night's sleep". W's answer reminded Amiya of a conversation between them during their times in Babel, which convinces Amiya to gave W the key that the Sarkaz promptly uses to access the controls. However, the key's access level turned out to be insufficient, much to W's shock, until Talulah gave W a second key.[16] With both keys in hand, Chernobog was finally stopped.
In the aftermath, W talked with Amiya, revealing that she knows the Chernobog control system's access code from Sergey – Misha and Skullshatterer's father – and she didn't expect the fact that Talulah is being manipulated by Koshchei all along; had she knew that fact, W could have prevented the deaths of many good people within the Reunion. W then bids her farewell with Amiya, hoping to never meet her again.

As Chernobog's core is on its way to a collision with Lungmen, W confronts Talulah at the Chernobog control tower, questioning her extreme measures. She seemingly agrees upon Talulah's justification, but the Draco eventually figured out that W intentionally sends Misha to her death earlier to deprive Talulah the key to the nomadic city's control systems, which she didn't deny.[13]

Realizing that Talulah had indeed changed, W attacked her, who retaliates with her Arts that W countered with her explosives. Throughout the fight Talulah questions W's motives before the Sarkaz reveals that she had placed explosive charges on the floor beforehand. When W tries to detonate them, it turns out that Talulah had "defused" the charges with her Arts, with Talulah using the opportunity to struck W down. Cornered, W detonates the explosives she had strapped to her body in a last-ditch attempt to kill Talulah; while Talulah survives the blast, W is seemingly killed.[13]

However, W barely survives and encountered the Doctor and Kal'tsit as they make their way to the sarcophagus where the Doctor is being kept before the events of Arknights' Main Story. Surprised to learn that Patriot is no more, W expresses her remorse to the death of an idealist like him; the Doctor told W that Patriot's death is a great one, prompting W to ask for an explanation from Kal'tsit, who refuses. W shows her disgust upon realizing that the Doctor and Kal'tsit are working together, questioning whether the Doctor is really amnesiac or not before pointing out that the Doctor is likely the one responsible for Theresa's death and Kal'tsit is "not truly a human".[14]

W then offered to help R.I. defeating Reunion, stating that Talulah, Theresis, and the Doctor are on her "hit-list", in that order. Kal'tsit accepts her offer, though her attitude annoys W; before she could make any trouble, however, Kal'tsit had Mont3r blast W through the walls with the Sarkaz vowing to get her for this.

Upon her return to the ruined Chernobog, W is welcomed by Mephisto. They promptly show their dislike for one another by exchanging bitter words before W confirms that R.I. had taken the bait. After pointing out that "the old-timer" is about to bring back the "real goods" and that Mephisto fears him, W asks for Mephisto to work together with her for now as they have a bigger fish to fry, which he accepts.

After Reunion's hideout is compromised by Exusiai and Texas, Skullshatterer asks W to protect Misha, a task she reluctantly accepts before suggesting that he ambush the joint R.I.-L.G.D. forces and kill the Doctor to disorganize them, which he agrees to.[7] Unfortunately, the ambush fails and Skullshatterer is killed by Amiya.

Nevertheless, W attacks the R.I.-L.G.D. forces after the foiled ambush,[8] but they managed to best her, at which point she throws a phone to Amiya, telling that someone wants to speak with her before using a flashbang to cover her escape as Reunion forces recover Skullshatterer's body.[9] W calms the Reunion forces who are panicking after learning of Skullshatterer's death and is reminded of her task to protect Misha by one of them. W talks with Misha, pointing out that she is the reason why the conflict happened in the first place and letting her decide what she would do next.[10]

Eventually Misha assumes the role of "Skullshatterer" and is killed in action alongside most of the remaining Reunion cell in a battle against the R.I.-L.G.D. forces. In the aftermath W makes a monologue about the fate that intertwines Misha and R.I. before concluding by stating that she is looking forward to seeing what would happen next.

While R.I. is pursuing Skullshatterer and his Reunion cell throughout Lungmen, W confronts Lungmen Guard Department under Ch'en's command who are protecting Misha[5] and manages to capture her.[6]

W follows Skullshatterer and his Reunion cell as they retreat through the wasteland between Lungmen and Ursus with Misha in tow.

During the devastation of Chernobog, W is first sighted engaging a Rhodes Island Reserve Team who are covering the main R.I. force's retreat. Adnachiel attempts to distract W and allow his teammates to fall back but W easily incapacitated (though not killed) him, prompting the rest of the Reserve Team to regroup and drive her off after a short skirmish.[2]

Despite the Reserve Team's efforts, W manages to ambush the R.I. main force. Recognizing the Doctor and Amiya who in turn don't recognize her, W asks the Cautus (Amiya) why R.I. is devoted to her, but she and the other team members respond with hostility, resulting in a fight.[3] In the aftermath, W, feeling "nostalgic", chooses to allow R.I. to walk away and leaves with her Reunion subordinates. However, she expresses the desire to meet them again sometime soon.

On the outskirts of Chernobog, W learns that a group of Sarkaz mercenaries has deserted and orders her men to stall the deserters. When she arrives, she discovers that they are led by a Sarkaz swordsman known as Flamebringer a mercenary who W considers an old acquaintance. She tells the Reunion troops to retreat unless they wish to die, and then the two Sarkaz converse. W invites him back to Reunion, but he rejects the offer. When he reveals that his only request is to have a fight and test Talulah's swordsmanship, she ridicules him. Flamebringer reveals that he witnessed the deal she made with Scout, and in response, W tells him that the person who commanded his old squad was the same one responsible for their deaths. She then allows him to walk away unharmed.

Who would have expected that the Sarkaz mercenary who once fought for Reunion against Rhodes Island on several occasions eventually had enough of her life as a mercenary and joined R.I.? She approached R.I. following the aftermath of the Chernobog-Lungmen crisis and offered her service "for old times' sake" and to "tie up the loose ends." With the contract signed, R.I. got itself a formidable mercenary skilled in using mass destructive explosives. However, her rebellious attitude and the various "old wounds" of other R.I. personnel earn W mistrust and suspicion. To keep her in check, Ascalon is responsible for monitoring her behavior at all times.

However, W's change of heart was motivated by her past. She was a loyalist of Babel, R.I.'s predecessor, and was especially attached to its leader Theresa. Upon her unexpected death three years ago, she vowed to seek vengeance for the former King and her best friend. Along with her colleagues Ines and Hoederer, W joined Reunion after hearing some rumors concerning Regent Theresis, the brother of Theresa whom she believed was responsible for her death. Since then, she has been looking for opportunities to carry out her vendetta against the Regent. This also explains why she never took her position in Reunion seriously – notably sparing Adnachiel's life in 1-11.
