Cosmic Princess Kaguya! Character Profiles
Iroha Sakayori
Iroha Sakayori is a high school student in Tokyo who juggles academics with part-time work and spends what free time she can in Tsukuyomi. Practical and often overworked, she initially approaches disruptions with understandable exasperation. Yet her caring nature comes through when she takes in a mysterious infant who quickly grows into Kaguya. Iroha becomes Kaguya’s producer and songwriter, helping her pursue streaming while their contrasting temperaments draw them closer.
Kaguya
Kaguya is a mysterious girl from the Moon who appears on Earth as an infant and rapidly grows to Iroha’s age. Curious and exuberant, she is captivated by Tsukuyomi and eager to become a streamer, with Iroha supporting her as producer and songwriter. Kaguya’s idealism and self-indulgent streak contrast with Iroha’s practical nature, but the two grow close as they pursue a happier ending than the folktale that inspired Kaguya’s name.
Yachiyo Runami
Yachiyo Runami is the charismatic administrator and host of Tsukuyomi, the virtual realm where users gather to explore new lives and creative pursuits. Welcoming to newcomers, she lends the world a theatrical sense of occasion and serves as a prominent figure for its streamers. She helps guide Iroha and Kaguya as they enter the Yachiyo Cup. Beneath her polished, approachable manner, Yachiyo remains enigmatic, with secrets tied to Tsukuyomi’s deeper nature.
Noi Komazawa
Noi Komazawa is a member of Black OnyX, the elite streamer group that stands as a formidable rival to Iroha and Kaguya in Tsukuyomi’s Yachiyo Cup. Like the team’s other competitors, Noi is confident and intensely competitive, bringing sharp-edged energy to the group’s public presence. The character’s place among these top-tier streamers helps establish the tournament’s high-pressure atmosphere, where skill, pride, and showmanship are all part of the contest.
Roka Ayatsumugi
Roka Ayatsumugi is one of Iroha’s close high school friends and a supportive presence in her life outside Tsukuyomi. Sociable and loyal, Roka offers a sounding board as Iroha tries to manage the demands of school and work. Her connection to Iroha’s everyday world provides a counterpoint to the extraordinary events unfolding in the virtual realm. Rather than seeking the spotlight, Roka helps keep her friend connected to familiar routines and relationships.
