Male / 175cm / 20 years old Characteristics → A Virtual Singer of Nightcord at 25:00, found in Mafuyu's Empty SEKAI. → He tends to isolate himself by choice, aware that he is perceived as an uncomfortable presence rather than making a good impression on the other Virtual Singers or the Nightcord members, especially Mafuyu. → He is always prickly and often experiences conflict with other Virtual Singers due to this personality. However, he occasionally shows tsundere moments. → Surprisingly, he likes ice cream and will sometimes smile if he has some. → He has dark blue hair and light blue eyes. → He is mindful of Len and harbors a certain degree of affection for him. Others → Since their first meeting, he pushed away Miku when she approached him out of curiosity about why he was angry. He also didn't speak to Rin for a while due to a misunderstanding after he was caught eavesdropping on Kanade's story. → He cares deeply about Len and Miku, and they are the ones he looks after the most. → Unlike the other Virtual Singers, he doesn't seem to care much about the Nightcord members. (In reality, he cares a lot but doesn't show it outwardly.)

Female / 158cm / 16 years old She feels calm and emotionless, but she simply doesn't know how to express herself. Instead, she tries to stay by one's side. She has the most otherworldly appearance with silver twin-tails, cyan and pink odd-colored eyes, a white dress, and bare feet.

Female / 152cm / 16 years old She has yellow hair with flipped ends and olive-colored eyes. She doesn't speak her feelings or thoughts honestly, but judging by the reactions of those around her, she doesn't seem very good at hiding her emotions.

Female / 162cm / 21 years old She has long, straight pink hair and eyes that are a mix of purple and blue. She has a fairly self-centered personality and only says what she wants to say, which leads to many arguments with other Virtual Singers in the same SEKAI, especially MEIKO and KAITO.

She has a brown bob cut and brown eyes. She shows the most distinct behavior among the Virtual Singers; since the others are good at helping, she believes someone needs to watch from a different perspective, so she always maintains a certain distance. Her personality is indifferent and sharp.
