Description
Asuka Kojou is a central character in Danbōru Senki W, introduced as a highly skilled and energetic LBX player. She is the older sister of Takeru Kojou, who is notably talented at building and customizing LBX units. Asuka carries the nickname Super Rookie, a testament to her rapid rise and impressive abilities in the competitive LBX scene.

In terms of personality, Asuka is overwhelmingly cheerful, carefree, and sociable, possessing a pleasant disposition that makes her easy to like. However, she can also be persistent, forward, and occasionally brash. She is very hyperactive and competitive, sometimes rushing into situations or jumping to conclusions without all the facts, such as when she falsely accused a teammate of theft before a major tournament. Asuka has a notable habit of putting her hands on her head and enjoys drinking tomato juice. Her demeanor and even her voice are somewhat boyish; she uses the masculine pronoun ore to refer to herself, which leads to her frequently being mistaken for a boy. Despite this, she has a more feminine side that appears on rare occasions.

As a player, Asuka is not just energetic but also intelligent, relying on sharp strategy and tactics in battle. Her skills are considerable enough that she was invited by the protagonist Hiro to join his team on a mission to save the world. She initially declined this request, suggesting she operates on her own terms. Her role in the story is that of a formidable ally and rival, and she becomes a champion of the Artemis tournament, a major competitive event. Her signature LBX unit is the Vampire Cat, and she is known to use a powerful special attack called Devil Soul, a technique that unleashes a massive burst of dark energy in battle. Her brother Takeru is a key figure in her life as the creator of her LBX machines, which highlights a strong and supportive sibling relationship at the core of her activities as a player. Throughout the series, Asuka is portrayed as a legendary figure, one of those who helped save the world from a major crisis. She is a professional at heart, once having a contract with a major corporation, but she ultimately chooses a path that aligns with her love for LBX as a hobby rather than a tool for conflict. Her professional career involves her working with the organization NICS, further cementing her status as a top-tier player.
