Akari Shiratora is a news anchor for Tokyo Tile TV, a television station in Tokyo known for being the weakest among major broadcasters, consistently ranking last in viewership for all programming except its news division. This station is also notable for being the only one that the influential D-REX Japan group, led by Kirika Kokuryū, has never attempted to take over. Akari carries the reputation of the station's news department on her shoulders, having established herself as a well-known and popular figure. She holds the tenth position in rankings of female announcers, a placement that is considered remarkably high for someone from her relatively small network.

In terms of personality, Akari possesses a direct and confident nature. This trait is clearly demonstrated when her company's upper management rejects a potential partnership with Haru Tennōji, the driving force behind the Trillion Game company. Rather than accepting this decision, Akari acts on her own initiative. She boldly goes to meet with Haru Tennōji personally, a move that defies her bosses' orders. Following their conversation, she becomes a devoted admirer of his vision and ambitions.

Her role in the story evolves from being a prominent media figure to becoming an important ally and observer of the main characters. Her key insight emerges during a meeting with Kirika Kokuryū. At that moment, Akari becomes the first person to articulate a critical distinction between the two powerful figures. She explains that while both Haru Tennōji and Kirika Kokuryū harbor grand dreams, their underlying reasons and ultimate goals are fundamentally different. This observation highlights her ability to perceive and verbalize the core motivations driving the central conflict of the series.

Akari's key relationships are primarily with the two protagonists and their rival. Her relationship with Haru Tennōji begins with her defiant pursuit of a meeting and evolves into one of strong personal support and infatuation with his character. Her encounter with Kirika Kokuryū is significant, as it is where she demonstrates her perceptiveness by distinguishing between the ambitions of the two rivals. Her professional standing as a top-tier anchor at a weak station gives her a unique perspective, making her an influential figure who can provide media exposure and articulate key thematic ideas. Her notable abilities include her professional competence as a popular news anchor, her strong will to act independently against authority, and her sharp perceptiveness in understanding the personal drives of the main characters.
