Megumi Ōkura is a character from the Cardfight!! Vanguard Divinez anime, where she serves as the current leader of the team known as Blackout. She is a young woman from a distinguished family, a "young lady" of a notable household who excels in academics, sports, and etiquette. Despite her privileged upbringing, she values self-reliance, demonstrated by her choice to work part-time at a card shop called Stray Cat to earn money for her own cards rather than using her family's wealth. By the time of the Divinez storyline, she is a university student, having already secured early admission to a university prior to the events of the series.

In terms of personality, Megumi is a passionate and fiercely competitive individual with a strong aversion to losing. While she is a refined and capable young woman, she also has a tendency to become easily excitable and is prone to overreacting or misunderstanding situations, which can lead to dramatic reactions. This combination of grace and fiery spirit defines her character. One of her most defining traits is her deep admiration and respect for Danji Momoyama, the former leader of Team Blackout, whom she affectionately refers to as aniki, a Japanese term for an older brother or respected senior figure. This admiration runs very deep and is a central motivation for her actions.

Megumi’s role in the story is significant, evolving from a core member of Team Blackout to its leader. She is also the person who introduces the protagonist of the previous series, Yu-yu Kondo, to the world of Vanguard at an abandoned night amusement park called Dreamland Wonder Hill. In the Divinez era, approximately a year later, she leads Blackout while balancing her university studies and her job, and has become so popular that she has a fan club at her school. Her key relationships include her bond with her teammate Tomari Seto and other members of Blackout, but her relationship with Danji remains the most prominent, acting as a major source of inspiration and a benchmark for her own growth as a cardfighter and leader.

As a cardfighter, Megumi uses a deck from the Stoicheia nation, specifically focused on the Sylvan Horned Beast archetype. Her primary strategy revolves around overwhelming opponents with a large number of attacks, often by granting her rear-guard units the ability to attack from the back row. While this eliminates the possibility of boosting those attacks, her deck compensates by providing those units with substantial increases in power to make them threatening. Her signature and ace unit is the grade 4 Sylvan Horned Beast Emperor, Magnolia Elder. Over time, she has shown the ability to adapt and refine her deck, even temporarily incorporating tactics from other fighting styles like the Uniformers for specific matches. Her development as a fighter is marked by her persistence and continuous training, leading to significant victories against strong opponents such as Danji Momoyama and Haruka Soukawa, although she has also faced defeats against formidable fighters like Michiru Hazama and Suo Yobitsugi. Her journey reflects a constant effort to grow from an admired member of a team into a strong and capable leader in her own right.
