Olka Gretcher

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 and pretended to be Furseal Grey's wife.

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

Appearance
Olka is a young woman 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.

History
The Gretcher family used to manage Ostania's underworld in an honourable 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 Furseal and gave him a loaf of bread, earning his loyalty.

However, her father and two brothers were killed in an internal dispute recently and the man who took over her family's organization put a bounty on her head. As a favor to her father, the Shopkeeper assigned Yor to protect her aboard the Princess Lorelei while she escapes to a foreign country by sea.

Furseal Grey
Furseal is deeply loyal to Olka, continuing to follow her despite being given the safer opportunity to follow the new boss that took over her family's organization. She is oblivious to his crush on her.

Yor Forger
Yor Forger is given the task of protecting Olka while aboard the Princess Lorelei. While being in the cruise, both of them get to have a good relationship since they understand each other’s situation and their need to protect the ones they love.

Trivia

 * Olka wore Blue Lace No. 88 and Mermaid Eau de Toilette on the ship.
