The Mole Hunt Arc is the fourteenth and ongoing story arc in SPY x FAMILY.

The lives of Westalian agents in Ostania are put at risk after a mysterious mole steals classified documents, one of which includes operations in Ostania like Operation Strix. The intelligence services of the two countries begin the pursuit of the thief and the stolen files in the hope of getting to them first.

Yor's Gripe
At Berlint City Hall, Camilla and Millie get stuck working overtime. Luckily for them, Yor offers her help, and Sharon is dragged along as well. After finishing all their work, Camilla, Millie, and Sharon agree to go out for dinner, and Sharon invites Yor to join them. Yor agrees but quickly gets drunk there, and the ladies discover a new side of Yor, which they find surprisingly hilarious and adorable. Camilla and Millie grill Yor for any gripes she has with Loid, but Yor cannot think of any, which they all find hard to believe. After the ladies share their gripes about their partners, Yor tries to fit in to appear normal, even attempting to drunkenly leave the restaurant with a butter knife to prove it. The girls accept Yor has a "lovey-dovey" marriage and tease her about getting intimate with Loid, then tell Yor that giving a welcome home kiss is normal for couples, which shocks her. When she returns home, Yor faints at the thought of giving Loid a welcome home kiss. Loid catches her from falling, but Yor ends up crashing around the house to prevent herself from hitting Loid, to his bewilderment.

The next day, Yor wakes up and worries that she made a fool of herself in front of Loid the night before. Meanwhile, Loid prepares Anya for her trip to the zoo with Becky. After Anya leaves with Becky and Martha, Loid sees Yor creeping into the living room. Loid remarks to Yor about how she overslept and worries to himself that she is dissatisfied with him after knowing how heavily she drank. On the other hand, Yor believes Loid is griping about her oversleeping and concludes that she should have a gripe too. Loid asks Yor to tell him any concerns she has about their life together, which only furthers her misunderstanding. Yor cannot think of anything and tries to be vague by saying that she has problems with everything, which astounds Loid.

Yor declares to Loid that she is dissatisfied with their life together. As she says this, a recovered Yuri bursts into the house for an impromptu hangout and is shocked by what he hears. From this point on, Loid struggles to resolve Yor's problem as soon as possible, but Yor wants a problem, and all the while, Yuri antagonizes Loid. The discussion is interrupted after Loid gets an emergency call - and secret emergency code - from the hospital and promptly leaves. Believing that Loid could be having an affair, Yuri convinces Yor to follow him but is forced to withdraw after receiving an emergency summons order from the Lieutenant. After Yor follows Loid to the hospital, she finally sobers up and heads home.

At the hospital, Fiona reports to Loid that they have an extreme situation: a mole from WISE HQ in Westalis has stolen important, top-secret files, one of which was a coded map regarding agents' operational activities in Ostania, including Operation Strix. At the same time, Yuri and other SSS agents are ordered by the Boss to ensure the mole's security upon crossing the border.

The Chase for the Mole
The mole is revealed to be Winston Wheeler, a talented spy whose abilities are praised by Twilight himself. The WISE agents make their way to Wheeler's supposed destination, Shellbury in northwest Ostania. Fiona is worried about the risk of this mission and suggests pulling the plug on every operation in Ostania and to restart with a clean slate. Loid refuses, reasoning that in Operation Strix's case, it would take years to get as close to Donovan Desmond again as they are now. Agents from both the SSS and WISE arrive at Shellbury, and Loid is tasked with keeping the SSS from getting Winston. At the same time, Winston receives orders to meet at the city's hotel. Disguising himself as Winston, Loid scouts the hotel from afar and spots disguised WISE agents waiting for the real Winston. In order to buy time to capture Winston, Loid approaches Yuri as Winston and tells him that he will change the meetup location to a park.

Meeting at the park, "Winston" and the SSS agents question each others' identities. Loid says his green tie and yellow gemstone tiepin was the signal that they specified. The agents report the color yellow to the Boss at HQ, who goes to chat with one of their officers, Jeffrey. The Boss reveals that a canary trap was set to reveal who was leaking their information by giving officers different colors of Wheeler's gemstone, then exposes Jeffrey as a mole working with WISE. Upon learning that Twilight is impersonating Wheeler, the SSS agents prepare to capture him. However, Loid is a step ahead and triggers several hidden traps around the park as he escapes.

Twilight vs Yuri Briar
Loid quickly disguises himself as Yuri and misdirects the SSS agents to another location before heading down the sewers. The real Yuri arrives at the park shortly afterward and notices that Twilight left behind a track leading to the sewers. Yuri gives chase but is almost killed by Loid, who hesitates upon seeing him. While both men are taken aback by their sudden appearances, they nevertheless shoot at each other. At the Forger home, Yor is still rattled by Yuri's suggestion that Loid is having an affair and wonders to herself if Loid will be coming home late.

The fight in the sewer continues, with Yuri's shot injuring Loid's right arm while Loid's shoots Yuri's gun away. Yuri is shocked to see Twilight posing as him and wonders if the spy could be someone close to him. Yuri focuses on capturing Twilight, and the two continue to fight in hand-to-hand combat, and Loid is surprised by Yuri's endurance. After knocking down Yuri multiple times, Loid ultimately comes out on top as Yuri finally collapses. Loid prepares to make a finishing blow but stops after hearing Yuri apologize to Yor and disappears further down the sewers.

Nightfall vs Winston Wheeler
Wheeler does not show up at the hotel, prompting Fiona and the WISE Agent to switch their plans, with the Agent putting on a disguise of Gascoigne, the SSS officer that Wheeler is supposed to meet. Wheeler, who has been waiting for a signal, notices "Gascoigne" leaving the area and tails him under the possibility that the meetup location changed. Still unable to lure out Wheeler, WISE agents stage a car accident. By observing the onlookers' reactions and poses, Fiona finally identifies Wheeler. Realizing he has been made, Wheeler attempts to escape but is cornered by Fiona and another WISE agent.

With nowhere to run, Wheeler surrenders. Fiona has the other agent secure Wheeler by tying his hands behind his back, then recovers the files he stole. Concerned that he has the intel memorized, Fiona and the agent begin moving him. However, in that instant, he jumps up, moves his arms back in front, and uses the bind to take the agent hostage. Wheeler proceeds to tell Fiona to drop the gun and threatens to kill his hostage, but Fiona ignores his threat, saying they are all prepared to die. The WISE Agent disguised as Gascoigne suddenly arrives on the scene, and, using this to his advantage, Wheeler throws the hostage at Fiona and jumps down the railing to the level below. After freeing himself with the knife the agent dropped, Winston escapes into a nearby sewage pipe. Fiona orders the Agent to aid their teammate and send backup, then continues the pursuit into the sewer.

Inside the sewer, Loid, still wearing the disguise of Yuri, is attempting to get to a safe zone when he starts hearing the footsteps of someone being pursued. Not knowing the circumstances, he decides to assess the situation first. However, Wheeler has already gotten behind Loid and attacks him. Loid tries to maintain his cover as Yuri to Wheeler, but Wheeler sees through the lies as Loid's footsteps were similar to his. Realizing he is talking to Twilight, Wheeler decides to unmask him, and they get into a melee. Fiona arrives at the scene of a defeated Loid as Wheeler is pulling the disguise off him. Consumed by rage, Fiona unleashes a forceful blow with her feet, stopping Winston in his tracks.

Elsewhere, Yuri is awoken by his teammate, Chloe, and the Lieutenant. Knowing Yuri was defeated by Twilight, the Lieutenant has Chloe bring Yuri to the surface for medical treatment and goes after him alone. On their way out, Yuri wonders why he was not killed but cannot put his finger on what that would suggest.

Returning to the spies, Fiona draws her gun at Winston, who pulls Loid toward him and threatens to kill him. He orders Fiona to throw away the gun, to which she angrily complies. Winston realizes that Twilight holds some importance to Fiona and reminds her that they cannot have any attachments in their work. He then says that he has a rule to never trust or invest anything in anyone, claiming it is what gives him a clear view of everything and makes him strong. Winston tells Fiona that she has no hope of beating him, but Fiona jumps at him with blind rage. Winston can read her attack, but the speed of her punch is so fast that it confuses him, and he barely manages to block it.

Fiona lands her punch on Winston, punching his arm into his face and breaking her right arm. Rattled, Winston struggles to get back on his feet. A narration explains that human beings are normally prevented by subconscious mental inhibitors from using 100% of their strength, as doing so would seriously damage their muscles and bones. However, in Fiona's case, she was so furious that all of her mental inhibitors broke. Fiona declares Winston weak for his inability to trust anyone, deeming him an empty man meddling with the world for his own amusement. She then says that her belief and thoughts of Twilight make her strong, and is why she will not be beaten.

Fiona lunges at Winston again, swinging her left arm at Winston but dislocating it when he dodges. However, she twirls from the miss and kicks Winston with a powerful blow of her leg, breaking it in the process. Winston is shocked but believes that with Fiona's injuries, he can try making a safe distance away from her. To his surprise, Fiona swings a hook at Winston with her dislocated arm, defeating him.

Seeds of Doubt
Fiona's hit knocks Winston out cold. Just as she is about to finish the job, Loid also comes to, telling her not to kill Winston. Together they tie him up, but Fiona begins to panic, wondering when Loid regained consciousness. They begin discussing everything that has happened that day, with Loid reasoning to Fiona that he was unable to kill Yuri due to how it would affect Operation Strix. After WISE Agent arrives, they begin to leave the area with Loid carrying Fiona while WISE Agent carries Winston.

On their way back, WISE Agent asks Loid to join him for a drink, but Loid declines, as he came out on the pretext of a work emergency and that it will be rather suspicious if he does not head back soon. Loid then goes on to talk about his troubles with Yor that morning. Fiona tries to accompany Loid to investigate and possibly try to set herself up to take over the wife role, but she is sent home due to her injuries.

Outside the Forger Residence, Loid is preparing himself to handle Yor's grievances. To his surprise, Yor is no longer mad as he falls to the floor in exhaustion and relief. Yor notices Loid is injured, for which he comes up with an excuse about a wrestler patient. Loid then asks about Anya, who is now fast asleep. He proceeds to apologize to Yor about her gripes, but she explains that she only made them up to seem normal. Gobsmacked, Loid collapses on the floor again. Yor asks if Loid needs an ambulance, but he shrugs it off and requests Yor to take care of the housework for him for the next two days, which Yor gladly accepts. Yor explains that it is not griping that she wants but rather to be able to take care of him and for him to share his burdens. She tells Loid that he does not have to be perfect all the time, but Loid, after fighting Winston and Yuri, believes that he must be perfect in order to survive.

As they finish their conversation, Yuri barges in. Noticing Yuri is hurt as well, Yor wonders out loud what has happened to everyone that day. Yuri makes up an excuse at work while Loid repeats his story about a wrestler patient. Loid then goes to prepare some tea, but Yuri notices that Loid is injured in his right arm. Remembering that he injured Twilight in the right arm earlier that day and that Twilight could be someone he knows, Yuri forcefully rolls up Loid's sleeves to check for bandages or the wound but finds nothing. Yor inquires what Yuri is up to, who makes up an excuse about Loid's safety. Yor then hurries Yuri away and tells Loid to take a shower.

Inside the shower, it is revealed that Loid had disguised his wound. Realizing that Yuri could tell he was injured, Loid reminds himself that a spy is as good as dead if he has a seed of doubt and to pull himself together. Coming out of the shower, he smells something burning: Yor has accidentally set his shirt on fire while trying to iron it, and Loid collapses on the floor once more.
