Reimu Endou is a female Colombian Virtual YouTuber affiliated with NIJISANJI EN's third wave "Ethyria", alongside Nina Kosaka, Millie Parfait, and Enna Alouette. She mainly speaks in English but makes occasional Spanish streams. She has pale skin and light hair that curls outward and upwards with light pink eyes and dark circles/baggy eyes.

She's also part of the unit Zuttoღo with Petra Gurin, Enna Alouette and Millie Parfait. In contrast to her melancholic lore and appearance, Reimu is a fairly upbeat and positive person who enjoys making sassy remarks and frequently engages in verbal banter. While often perceived as hot-blooded when interacting with her fellow Livers, she genuinely enjoys their company.
