Yelena is the leader of the Anti-Marleyan Volunteers working under Zeke Yeager. She was one of the Marleyan soldiers on board the first survey fleet to Paradis Island after Marley's failed attack operation. She is a very tall woman with her blonde hair styled in a short bob with straight bangs. She has large dark eyes and somewhat androgynous features due to her build and style.

Yelena is a fervent follower of Zeke Yeager, holding great admiration and respect for him. She is usually calm and collected, her demeanour remaining unchanged even when Jean Kirstein yelled at her for failing to see her job through. Nonetheless, she is willing to take responsibility and apologizes should she fail in her task. Yelena appears to maintain a very relaxed demeanour while having dry, humorous undertones to much of her actions.

It is later revealed that Yelena was born into an unassuming family in Marley, and eventually became disillusioned with her own country. After meeting Zeke Yeager, Yelena concocted a plan to solidify herself in history by helping Zeke save the world. As part of her narrative, Yelena created a false background for herself, claiming that her homeland was invaded and conquered by Marley. She was forcibly drafted as a soldier to fight in the Marleyan military, where she met similar-minded soldiers and organized them into the Anti-Marleyan Volunteers to fight against Marley.
