Description
Anju Kitahara is a character who appears as a childhood friend of Yuu Matsuura. She is a girl with a gentle and calm demeanor, known for being very kind and polite, though she is also quite introverted. Physically, she is depicted as a teenage girl with blue eyes and short, neck-length blue hair.

Anju and Yuu first met when they were both in the sixth grade, around the age of twelve, and they quickly became close friends. For a period, they spent a great deal of time together until Anju moved away, leading to a separation of about five or six years during which they lost contact. She later moved to the same area as Yuu, and their reunion occurs unexpectedly at a train station when he returns from a trip. Upon seeing him for the first time in years, she approaches him and asks if he is Yuu Matsuura, reminding him that they used to play together, and that her nickname is Ann, a name only he uses for her.

Regarding her personality and motivations, Anju has harbored romantic feelings for Yuu ever since their childhood. Despite this, her character is defined by a selfless and considerate nature. She is aware of Yuu's relationship with the protagonist, Miki Koishikawa, and explicitly states that her intention is not to come between them or to separate them. She confesses her feelings openly, expressing that she is content simply to be second in Yuu's heart, acknowledging that it would not be right to try to take him away from Miki.

A key aspect of Anju's background is her fragile health. She is described as having a sickly body. During her reappearance in Yuu's life, she informs him that she is facing a very risky surgery and may not survive the procedure, which adds a layer of poignancy to her confession of love. Her role in the story is primarily as a catalyst, appearing as a gentle rival whose presence tests the strength of the bond between Yuu and Miki. Her development is centered on her honest confrontation of her own feelings and her graceful acceptance of the situation, choosing to cherish her connection to Yuu without demanding that he leave his girlfriend. There are no notable abilities or special skills attributed to the character.
