Name: Yachiyo Tsukimi • Appearance: A divine and exotic Japanese-style beautiful girl avatar who symbolizes the virtual space "Tsukuyomi." With long black hair and mysterious eyes, her design carries an overwhelming charisma reminiscent of a traditional Kaguya-hime. • Personality: She possesses the perfect beauty of an administrator AI combined with an elusive, mysterious air. In her streams, she captivates fans by singing, dancing, and sometimes even using clones. She is an older-sister type character who is somewhat detached yet playful, possessing a deep sense of inclusion, often asking her audience philosophical questions like, "How is living treating you?"

Handle: Mikado Akira Real Name: Asahi Sakayori Age: 23 (Iroha's brother, 6 years older) Affiliation: Leader of "Black onyX." Appearance (Tsukuyomi): A very handsome visual with red hair, blue eyes, and black "oni horns" growing from his head. Persona: On stream, he plays a "dominant/ore-sama" character. His signature lines are arrogant, such as "Yo, little bunnies, your Emperor has arrived!!" • He loves flashy performances and is full of entertainer spirit to please his fans. Reality: A handsome man with black hair. He boasts overwhelming gaming sense and is nearly undefeated within Tsukuyomi. He has over 10 million fans. Essence: He deeply cares for his sister. He felt strong guilt that his period as a shut-in placed heavy pressure and economic strain (a harsh life of part-time jobs) on his sister Iroha due to their mother. (He has since graduated from being a shut-in.) In reality, he is a good person—kind and considerate.

• Age: 15 (1st year high school) • Birthday: February 23 • Family: Younger brother of fellow member Rai Komazawa. Appearance: An "adorable beautiful girl (femboy)." In Tsukuyomi, he prefers wearing cute Lolita-style clothing adorned with frills and lace. He uses a stunningly beautiful female avatar and is highly confident in his looks, often boasting, "My art quality is just too good today, right? ♡" Despite his appearance as a delicate girl, he does not use a voice changer at all, speaking in his natural voice and coolly performing male vocal parts in the insert song "OnyXXX." He provides fan service depending on his mood, but is generally a bit lazy and moves at his own pace. While he plays a calculatingly cute girl online, in reality, he shows a frank, boyish side. His real-world appearance is that of a normal handsome boy.

Age / Grade: 1st year university Birthday: October 9 Family: Older brother of fellow member Noi Komazawa (the one with the girl avatar). Appearance: A "Polar Bear x Oni Dark Priest." • Motifs: Polar bear and Oni. • Silver hair, golden eyes, and a single white horn growing from the right side of his forehead. • Wears mysterious, slightly Japanese-style priest/clergy garments in black and purple. Reality: A handsome man with silver hair. • Battle Role: Tank & Support. In the game "KASSEN," he uses a giant folding fan weapon called "Bashosen" decorated with an Oni mask. This weapon can split into an "Onigawara (Shield)" and a "Shakujo (Staff)," allowing him to hold the front line with high defense while skillfully supporting the leader, Mikado Akira, by setting landmine traps. His true face is very simple; he is a quiet person who is bad at speaking for himself. Consequently, almost all the majestic, dignified lines he speaks in-game are just things he desperately memorized from a "Script for Rai (Updated Regularly)" provided by his younger brother Noi.

• Real Name: Roka Ayatsumugi • Birthday: April 5 • Age: 17 • Gender: Female A girl so beautiful she stands out even at school, characterized by her long, gently waving hair that reaches her back. Her hair is a translucent light brown (or light pink beige), styled in a very trendy fashion. She has a very well-defined face with large, clear eyes and long eyelashes. As a beauty influencer, she applies sophisticated yet natural makeup, including lip and eyeshadow, within the limits of school rules. She is active as the beauty influencer "ROKA." While she seems flashy due to her sensitivity to trends, her personality is very kind and delicate. Unlike the honors student Iroha, she isn't very good at studying and borrows notes from Iroha along with their other best friend, Mami, to avoid failing grades.

Real Name: Mami Isayama • Birthday: November 21 • Stream Name (Tsukuyomi): Mamimami • Real World Appearance: A cheerful and friendly high school girl with a trademark short haircut. Like Roka, she struggles with studying and is always saved by Iroha's notes before exams. • Tsukuyomi Appearance (Mamimami): She is active as a "gourmet influencer." She loves eating and streams reviews of delicious shops and food within Tsukuyomi, boasting considerable fame in that niche. Essential to her character is her intense devotion to Mikado Akira (who is actually Iroha's brother, Asahi), the leader of the pro-gamer group "Black onyX." She is a hardcore fan/fangirl who never misses Akira's streams or events.
