Description
Airi Katagiri is a high school student who works alongside Satoru Fujinuma at the Oasi Pizza delivery service. She has waist-length brunette hair with a fringe across her forehead and dark eyes. Her typical outfit includes a blue school shirt with a red ribbon at the collar, a navy checkered skirt worn above the knees, and black socks with loafers. Her personal style includes a cylindrical, mint-colored bag with navy straps that has Chick Charms attached to it.

Airi has an optimistic and highly reliable personality. She believes strongly in expressing one's desires and beliefs out loud as a way to make them come true. She tends to be playful with Satoru, often joking about his serious and strict demeanor. Like him, she can be blunt and direct with her thoughts, expressing them in a mature manner without much concern for others' opinions. She also holds a deep interest in photography, as she feels that pictures never lie and capture the truth of a moment. Her loyalty is one of her defining traits, as she demonstrates when she chooses to listen to Satoru, gives him advice, and even lets him hide in her house when he is accused of a terrible crime.

Airi's motivations are rooted in a significant childhood event involving her father. When she was in elementary school, a chocolate bar fell from her father's pocket while they were shopping. The store owner, who knew the family, was willing to drop the matter if her father would admit to stealing it and apologize. However, her father refused to admit to something he had not done, insisting on his innocence. This led to the police being contacted, and her father, a member of the local agricultural cooperative, was suspended for three months. The incident resulted in her parents' divorce, and her mother believed the accusations against her father. Years later, her mother expressed deep regret for not having believed him. This experience taught Airi the pain of being doubted and instilled in her a powerful desire to believe in others for her own sake. She helps Satoru not just for him, but to live up to her own belief that trusting people is a source of personal strength.

In the story, Airi becomes involved with Satoru after noticing unusual events surrounding him, such as when he manages to save a child from a dangerous fall from an abandoned building. She is one of the very few people who decides to trust Satoru unconditionally when he is framed for the murder of his mother, Sachiko Fujinuma. She provides him with crucial emotional support and a place to hide from the authorities, putting her own life at risk. Her faith in him gives Satoru the courage and hope he needs to continue fighting to clear his name and uncover the truth. After Satoru wakes up from a fifteen-year coma and begins to regain his lost memories, it is Airi who he reunites with under a bridge while taking shelter from the snow, restarting their connection.

Her key relationships are primarily with Satoru, built on a foundation of trust and mutual respect. She admires his selflessness, and he draws strength from her unwavering optimism. She also shares a close bond with her cousin, Miho, who lives with her in Chiba. Miho is a source of support for Airi, reminding her of her strengths during difficult times. She also interacts with her boss at the pizza shop, who, despite being critical of her work at one point, seems invested in her growth as a photographer.

Airi undergoes clear development throughout the narrative. Initially a high school student with a strong moral compass, she demonstrates remarkable bravery and maturity when she defends Satoru. Her experiences with him deepen her understanding of trust and sacrifice. In the changed timeline, she pursues her interest in photography and becomes a professional photographer as an adult. When she faces criticism from her boss that leaves her feeling defeated, she finds the resolve to smile again and start over, deciding to speak to the first person she meets, who is Satoru.

Airi does not possess supernatural abilities. Her notable strengths are her emotional resilience, her unshakable loyalty, and her powerful belief in the importance of trust. She has a talent for photography and uses her intuition to perceive oddities in events that others might overlook. Her simple phrase, are you stupid?, which she often says to Satoru, echoes a phrase used by another important person in his past, adding a layer of significance to their connection.
