Olka Gretcher

"Those hands of yours, are the reason this child has a future. I know this might not be possible for you. And maybe I should just mind my own business. But I want you to know… I will be praying… for you and your family to find peace happiness."

- Olka Gretcher to Yor Forger in Chapter 55

Olka Gretcher (オルカ・グレッチャー) is Yor Forger's client, who she is tasked to protect while aboard the Princess Lorelei. She travelled under the name Shaty Grey (シャティ・グレイ) and pretended to be Furseal Grey's wife.

She is one of the last remaining members of the Gretcher family, alongside her only son Gram Gretcher.

Appearance
Olka is a young woman wearing glasses with short hair and messy bangs. However, her current appearance is a disguise to help her travel incognito. In an old photo of her, she is shown to originally have long black hair tied into a low ponytail.

Due to her need of hiding and avoiding the assassins, her clothing changed constantly, not having any standard clothing. Her last clothing consists of a white opened coat with a dress and black heels.

Later in the cruise, she puts on a short black wig with a bow on the back.

Personality
Olka is shown to be a kind and generous woman who is willing to do anything to protect the ones she loves and to save anyone who is needed, as she gave Zeb some food to save him when they were younger. When Yor first met her, she seemed quite serious and direct (and is understood as she lost most of her family), but she still was kind towards her and respects her motives. As the time passes by, Olka begins to trust more in Yor and her capabilities, but also starts feeling fright for everything going around the cruise and her situation, but tries her best to stay calmed and relaxed to keep her child Gram calmed too.

History
The Gretcher family used to manage Ostania's Underworld in an honorable fashion. After the war, her family ran a black market that distributed food to people on the streets. During this, a young Olka encountered a young Zeb and gave him a loaf of bread to eat, earning his loyalty.

However, her father and two brothers were recently killed in an internal dispute and the man who took over her family's organization, Leonardo Hapoon, put a bounty on her and Gram's heads. Going into hiding, Olka and Gram sought temporary shelter in a safe house. Wanting to leave her life behind, Olka chose to escape and seek asylum in a foreign country, by being a passenger of the Princess Lorelei, and at the port of disembarkation she will take another ship that will take her to the country, with the company of Zeb disguised as her husband. As a favor to her father, the Shopkeeper of the Garden assigned his assassins to bodyguard her on the ship.

Cruise Adventure Arc
Aboard Princess Lorelei, Matthew McMahon introduces himself as the Director of Policy at Berlint City Hall and two bureaucrats from their business development team, Heymann and Vides. Furseal presents himself as a member from Arhaus Department Stores and Olka, as Shaty Grey. The two bureaucrats offer to give the Greys a tour of the ship, though Olka refuses while citing the need to take of her baby. As the group leaves, Furseal expresses concern for leaving Olka and him alone, so Matthew assures him that Yor is strong.

Now alone with Olka, Yor inspects the suite for possible entry and escape routes. Yor talks with Olka, who says Furseal is a member of her crew playing a part, and she talks about her desire to live a quiet life with her son. Olka then requests that she and her son go outside for a short moment. Yor is initially hesitant, but Olka says their enemy does not know what she looks like and knows that Yor will protect her, and Yor accepts. As they prepare to leave, Yor nervously looks outside the door. Olka questions her actions, and Yor says her family is also aboard the ship.

Yor explains to Olka that her family's presence on the ship is a coincidence and that they are unaware of her real job. Olka asks if they are for her cover identity, and Yor confirms it with a tender look on her face. Gram starts to cry, reminding Yor of their plan to go outside. Olka stops Yor to lend some clothes for a disguise. When they go outside for fresh air, Olka is wistful about leaving her old life behind. Her son starts to sneeze, so they decide to head back. Yor promises to give it her all and finish the job for Olka and her son. Her words move Olka, so she reveals her son's name. and offers to let Yor hold him.

Later, the City Hall group and the Grey family have dinner at a fancy restaurant. After dinner, Yor escorts Olka and Gram back to theur room. Once inside, Olka notes there has not been any sign of trouble the entire day, but Yor warns her that they must keep their guard up as they have no idea of where the enemy is or their plan. She predicts that the enemy will try attacking at the last possible minute, which will be the next day. Olka asks what everyone else will do if she manages to escape safely, and Yor explains their prepared cover story. Olka then asks if Yor will see her family after she completes her mission, as the ship will stop at a resort island on the third day. She suggests that Yor could use it to spend time with her family, but Yor is hesitant. Sometime later Olka decides to get changed for the night, but suddenly the women hear someone knock on the door, wondering who it could be.

Yor looks through the peephole and sees a waiter with room service. Yor is relieved and tells Olka about this, but she says she did not order anything. Yor hears a gun click behind the door and quickly moves Olka and Gram to safety, much to her shock. After the assassin was murdered and retrieving the corpse, Matthew informs the group that the itinerary got leaked and there are multiple enemies aboard the ship. He directs Yor to take the Olka, Gram and Furseal to a vacant room in the second-class suite while he covers up the mess. After receiving domino masks to disguise themselves, Yor, Olka, Zeb, and Gram leave for the second deck lounge.

Upon arriving there, Nearby, an assassin is dispatched to kill Olka, but Yor stops him, grabbing his hand. She acts as if she was invited to a dance and dances the man away from Olka. Yor returns to her, Gram and Furseal and decide to go through the shopping promenade to the second-class area. There, Yor protects the group from a surprise attack by an assassin, Sickle-and-Chain Barnaby. Yor manages to defeat the assassin before resuming their move to the new room.

After arriving at their new room, Yor assures the group that the room is secure and has everything they need to hole up safely until the rendezvous. Gram starts to cry, and Olka tries to comfort him, though she herself is shaking. Furseal notices this and exclaims how scared he was of their attackers. Olka and Gram disapprove of Furseal's cowardice, while he is satisfied seeing them calm down.

Olka asks Furseal, calling him by his real name Zeb, why he came with them instead of joining the gang's new boss. Zeb says he does not forget how much he owes to the previous boss. He recalls how he would have been dead if not for the black market the Gretcher family ran after the war and flashes back to a young Olka secretly giving him bread. Zeb remembers this fondly and says it is all the reason he needs to be with her. Zeb promises to protect Olka from harm but relapses when he hears a knock on the door, and he quickly puts behind Olka.

Standing by a radio, Matthew receives a transmission and calls Olka Gretcher's room. Yor answers the phone and informs the others that they got the all-ready signal from the ship at the rendezvous. While it will be in four hours, Yor tells Olka and Zeb to prepare and change into their disguises. After seeing that the coast is clear, Yor, Olka, Gram, and Zeb head out.

As the fireworks show is about to commence, the group walk through the halls of the ship. Yor says their destination is Storage Area 3 and explains the plan to get Olka off the boat and to the rendezvous ship hoping to proceed during the fireworks show, but the show starts, the group is startled by the sudden noise. Gram starts to cry, so Olka coos her baby telling him how beautiful the fireworks are. After calming down, they continue onward. From above, a sniper watches them and prepares to shoot Olka as another firework goes off. Yor quickly grabs Olka out of the way but gets grazed by the shot. Yor asks Olka and the others if they are alright. Suddenly, a large number of assassins reveal themselves and surround the group.

As the assassins surround Olka and the group, Yor sees no escape. Yor tells Olka and Zeb to hide inside a hatch, but she gets held back by a rope user when she tries to guide them there. While Olka and Gram go inside the hatch, an assassin points his gun at them. Zeb sees this and grabs Olka, shielding her from the bullets fired. As they tumble inside the hatch, Zeb shuts the cover. A worried Olka asks Zeb is he is okay, and he complains about how badly he is hurting even while wearing a bulletproof vest, so Olka tells him not to be so reckless.

After Yor and Matthew exterminate all the enemy assassins, Olka and Zeb get out of the hatch and Yor and Matthew prepare the inflatable boat for them. While Matthew gives Zeb instructions, Yor wishes Olka a great life on the other side and receives a hug as thanks. Despite Yor's protests because of her soiled hands, Olka has her hug Gram, saying that her hands are the reason he has a future. Yor appreciates the gesture and embraces the child, remarking how warm he is. Before leaving, Olka says she will pray for Yor and her family to find peace and happiness.
