—Nari Amatoya, Corpse Party (ExChap 1)
Nari Amatoya (天戸屋 成 Amatoya Nari ) is a student from Musashigawa Girls' Middle School's class I-6, a victim trapped inside Heavenly Host Elementary School, and a character introduced in Corpse Party (PC).
Nari is a young teenage girl of above average height and slightly below average weight. She has short chestnut-colored hair, a silver hairpin with a red sphere on it and purple eyes. She wears the Musashigawa Girls' Middle School uniform which consists of a white shirt, a beige blazer, a skirt, a blue bow tied around her neck, black shoes and white crew length socks.
Nari easily loses patience and is quickly annoyed. However, she keeps a cool head and doesn't whine or cry. Despite seeming cold, she cares about her friends and doesn't want to deal with any dangerous situations.
Nari performed the Sachiko Ever After ritual for fun with several of her friends, sending them to Heavenly Host Elementary School. When she arrived, she was with her friends, Nana Ogasawara and Chihaya Yamase, with the other three who performed the charm nowhere to be found.
The three searched the school for their missing friends for several hours, until eventually meeting the ghost, Takaomi Shimoda, who Nana met in the boys' lavatory. Takaomi explains that his glasses and hat were stolen by another ghost, and the girls decide to assist him in recovering them, with Nari voicing her opinion on their current goal, calling it ridiculous. Eventually they recover both the items, and receive a confidence boost for doing so. After this, they resumed the search for their friends.
At some point, the girls were captured and killed. Nari's cause of death is unknown, only her name tag is found, which gives no clues to how she died. The game explains her death as, "exact circumstances of death unknown."

Scared and shocked at how Sakutaro could do that with a smile on his face, Nari and Chihaya decided to get away from Sakutaro and the two of them leave shortly after he notices them trying to run away.
