|Relatives||Unnamed Sister †
Parona is a young girl around the age of 15. She has long black hair that is tied in a loose ponytail. She wears a dress with cloth wrapped around her arms and legs.
Parona is clever, observant, courageous, and selfless. She strongly disagrees with the Ninannah tradition of sacrificial ceremonies.
As a child, Parona often played with a young girl she referred to as "big sis". One day, her sister took her into the forest and asked her to play a game - hide and try not to be found. She said the game would end when she came back and left Parona with food that would last for a couple of days. After an unknown amount of time, Parona came out of hiding and asked an older woman where her older sister went. The older woman told Parona that the girl was no longer there because she was chosen as a sacrifice for the Spirit Bear. Parona ran away, criticized by the villagers, and eventually found her sister's body lying in the forest.
Spirit Bear Arc
March is seen playing house with her dolls and Parona surprises March with a new doll in the shape of a crab. She plays with March until dinner time.
The next day, Parona is practicing archery using a big, heavy bow instead of a lighter, smaller one. Each time she shoots, she misses. March arrives and asks Parona if she wants to play, but Parona refuses, saying she would like to train today but that they can play tomorrow. Later that day, a sound is heard throughout the village. Parona asks March if she wants to play and tries to take her into the forest but is stopped by Hayase. Hayase asks if they heard the villagers' signal to assemble and tells them to go to where everyone else is. Parona is then seen several days later at March's departure, staring at her with a pained expression.
As March and Hayase are making their way up the mountain, an arrow flies toward Hayase and March takes that opportunity to escape. As March runs away, Hayase chases after her but Parona appears and knocks Hayase down.
Parona treats March almost like a little sister, playing house with her, protecting her and almost committing suicide after March is killed. She admires March's innocence and dreams of becoming a mother, realizing what lengths her older sister went to keep her safe and vows to do the same for March. She finds the strength to keep going by Fushi, telling her that March wouldn't have wanted her to despair over her death. In March's version of the afterlife, Parona is there, smiling and playing with her.
Parona dislikes how Hayase uses the people in the village for her own ends and even goes to the lengths of sacrificing March. The two hate each other to the point that Parona holds no remorse in trying to kill her, even grimacing in distress when instead of shooting her head when aiming at Fushi, she instead shot her hand. Hayase hints to Fushi that she tried to take off Parona's face, but she also ended up beheading her in the process because she just wouldn't stay still.
When Hayase's descendant Kahaku becomes infatuated with Fushi using Parona's form and wants to marry her, Parona is disgusted by this and causes Fushi to throw up. Even as a spirit, she refuses to want to have anything to do with Hayase, hating the woman who not only killed her adoptive sister but also took her life.
Parona practices archery with a big, heavy bow. Because of the bow's weight, her aim is off and she ends up missing a lot, but if her bow is the correct weight, her aim is adequate.
- Strategy Making
Parona is also capable of making tactics. While in Yanome prison, she was able to formulate an escape plan and use the tools she gathered as weapons. 
When not using her bow, Parona can be very adept at fighting with just her fists, She hides a hidden blade on her body so she can see through her bindings and even be creative enough to fashion a spear out of a nearby mop when attacking her prison wardens.
She's very lithe, easily able to climb structures and run quickly.
