Name: MIMI Gender: Male Birthday: Jan 21 Debut: June 9, 2016 Representative Songs: Bouquet, Hollowing, Hug, To Live Other: A Vocaloid producer (Vocaloid P). He composes songs with a lyrical yet somewhat fast-paced atmosphere. Most of his tracks feature a characteristic piano melody as the main theme, giving his work a consistent vibe. Because of this, anyone who enjoys his basic melodic style will find most of his songs easy to listen to. While some mistakenly believe all his songs are the same because his famous tracks are lyrical piano rock, he actually writes across a wide range of genres including waltz, swing, and ballads. He primarily uses KAFU for vocals, but occasionally uses Miku or Teto. Outside of Vocaloid production, he composes and covers piano pieces. He enjoys healing by watching videos of baby seals. His MBTI is INFP.

He mainly uses GUMI, v flower, and Xin Hua, though he has also used Kagamine Rin/Len, Hatsune Miku, and Yuzuki Yukari. Recently, he has been using Kasane Teto as well. His work is characterized by addictive melodies that stick in the mind, flashy basslines, and gloomy, complex lyrics. His use of unique Electro Swing rhythms is a particular highlight. He gained significant recognition after his 2016 upload 'Fragile' became a massive hit.

Name: Iyowa Gender: Male Birthday: Sept 23 Debut: 2018 Representative Songs: Kyu-kurarin, Living Millennium, Heat Abnormal, Peach-Colored Key Other: A Vocaloid producer (Vocaloid P). He is a Japanese freelance composer and lyricist. He is a multi-creator who handles not only the music but also the videos, illustrations, mixing, and mastering; he occasionally creates videos for other Vocaloid producers as well. He is a member of Studio Gohan, an animation team centered around Harumakigohan. His stage name comes from "I ga yowai" (weak stomach). His Piapro ID is "igayowainoyowatashi" (My stomach is weak, you know) and his Twitter ID is "igusuri_please" (Stomach medicine please), suggesting he might suffer from chronic stomach issues. However, according to his comments on the upload of 'Over!', he isn't in as much pain lately due to dietary management. He likes light pink and has a timid personality.

Name: Orangestar Gender: Male Birthday: Aug 20 Debut: April 2, 2013 Representative Songs: Night Sky Patrol of Tomorrow, Earphones and the Cicadas' Song, The Rotating Sky Rabbit Other: A Vocaloid producer (Vocaloid P). He primarily uses IA, and occasionally Hatsune Miku. He mostly composes songs with a summer feel, which is why his song thumbnails often use blue tones. His work is characterized by dramatic piano melodies and drum beats. He frequently uses words like 'tomorrow', 'sky', 'night', and 'incomplete' in his lyrics. He is often referred to as 'Mikansei-P' (Incomplete-P).

Name: Kairiki Bear Gender: Male Birthday: Sept 30 Debut: June 2, 2011 Representative Songs: Venom, Failure Girl, Angel, Bug, Darling Dance, Alkali Underachiever Other: A Vocaloid producer (Vocaloid P). He creates rock music with gloomy lyrics based on addictive guitar riffs and makes clever use of Katakana. He puts immense effort into the guitar parts; for example, the synthesizer-like guitar riff in the intro of 'Darling Dance' was created by recording every single note himself and splicing them together in a program. The number of these spliced notes exceeds 2,000, and he reportedly recorded until he got the perfect muted picking sound for every single one, making the total number of takes dizzying to imagine. While he is sometimes criticized for self-repetition because his song structures—unique guitar intros, highlights with repeating words, and climaxes that drop the accompaniment for solo vocals—are often identical, most of his new releases continue to enjoy explosive popularity.
