Airi Katagiri

Airi Katagiri is a high school student and Satoru's co-worker at Oasi Pizza. She gets involved with Satoru when she realized oddities as Satoru managed to save people from life-threatening incidents, and was one of the few who decided to trust Satoru when he was framed as his mother's murderer.

Appearance
Airi has waist-length, brunette hair, with dark eyes with a fringe, spread over her forehead. 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.

Personality
She has a bright personality and is quite reliable, as shown when she helped Satoru. She can also be quite aggressive when she doesn't agree with someone' intentions.

History
When she was in elementary school, she and her dad went grocery shopping. A chocolate bar fell out of his pocket. Since it was a small town, they knew the owner. If he admitted to stealing it and apologized, the owner said he would let the matter drop. But her father wouldn't admit to it. She says that it was the first time she heard him yell. The owner felt obligated to contact the police, and her father, a member of the local agricultural coop, was suspended for three months as punishment. Her father quit the coop, got a divorce, and left home. Her mother thought that he really did steal it.

She currently lives with her mother's older brother and his wife. Her parents live out in the country. She was going to find a boarding house so she could commute to high school, but they invited her to stay with them in Chiba. Years later, her mother expressed to her that she regretted not believing in him.

After Satoru wakes up from his 15 year coma, she punches a camera man attempting to take a picture of Satoru with Kumi no longer knows who Satoru is. After his memories return, she meets Satoru in their former meeting place while taking shelter from the snow.
