What is the name of the protagonist in 'The Tale of the Princess Kaguya'?

The protagonist in “The Tale of the Princess Kaguya” is Princess Kaguya. She is discovered as a tiny girl inside a glowing bamboo stalk by an elderly bamboo cutter, who raises her with his wife. The child grows extraordinarily quickly, so the villagers nickname her “Little Bamboo.”

Her adoptive father later moves the family to the capital, where she is formally named Kaguya-hime, meaning “Princess of Shining Night.” Her beauty attracts five aristocratic suitors and even the Emperor, but she rejects them through impossible tasks drawn from the older Japanese folktale “The Tale of the Bamboo Cutter.”

A common mix-up is confusing Kaguya with the people around her. Miyatsuko is her adoptive father, Sutemaru is a childhood friend, and Menowarawa is one of the household girls. Kaguya herself is the central character, and the film follows her struggle between earthly life and her celestial origins.
