Airi Katagiri

Airi has an optimistic personality and is quite reliable, as shown when she helped Satoru on multiple occasions. Airi believes it is important to express one's own desires and beliefs out loud in hopes of making them a reality one day. She tends be playful with Satoru, often joking about his strict personality. Similarly to Satoru, Airi tends to be blatant and often expresses her thoughts out loud, but in a rather mature manner with little interest of someone else's opinion. When Satoru is accused of murder, she demonstrates her loyalty by not only listening to him and giving him advice, but letting him hide out at her house. Airi holds a certain interest in photography, as she believes that pictures never lie.

Airi has waist-length brunette hair that has a fringe spreading over her forehead and dark eyes. As a high school girl, she has a typical uniform, a blue shirt, with a red ribbon around the collar, a navy checkered skirt above her knees, with black socks and loafers. Her bag's straps are navy and the bag itself is cylindrical and mint-colored, with Chick Charms attached on to it.
