Well, the original notation is sasakure.UK, but since UK is pronounced as Yukari, I'll write it as Yukari. Male Vocaloid producer and BMS creator Age undisclosed (for some reason) Japanese The music has a very cute chiptune feel, but there are many songs related to the apocalypse (it's even more surprising that there's an apocalypse series). Seems to like pixel art. Seems to enjoy rhythm games (and is good at them;) Appeared on a live broadcast on Niconico Douga and was said to be extremely restless and energetic (one might think he was nervous, but he said himself he's just like that...) Origin of name: Hangnails (sasakure) often occur on his fingers.

Is he on drugs?? (Just kidding) Male Vocaloid producer 22 years old Japanese This one is also chiptune, but it's very soft and cute, yet he adds a ton of dissonance and glitch effects (creates a menhera vibe...) Small number of songs (the last song was 2 years ago... is he dead?) Originally aimed to make games, but while studying music, he got drawn into the Vocaloid scene and became a Vocaloid P (wow). Actually can't play any instruments (makes all music on the computer). Origin of name: A pun on being depressed. Draws well but says he's bad at it (he's actually good). Playful but since he's menhera, his mental state seems unstable!

Crazy Female 25 years old Vocaloid producer Japanese Makes very cute, bouncy, and adorable music, but the content is often shocking, involving suicide, grotesque themes, murder, R-18, etc. Has had 2 songs deleted from YouTube (1 was flagged as R-18). Has ADHD (possesses a disability certificate). Has a younger brother. Likes snails! Has her own original character universe called PoyoPepu! Draws in a round, cute style. Used to draw R-18 art often, but seems to be lowering the intensity recently. Cheerful!

Suspected of having depression (seriously.) Male Vocaloid producer 37 years old Japanese (The music) is truly vicious(?) The lyrics are about suicide... R-18... Good Child Syndrome... sexual violence... might be worse than Pepoyo? Still, his personality is active (how come..?) Many songs have been victimized on places like TikTok (T_T) Actually has a mental illness, but it has improved a lot. The music atmosphere uses xylophones and music boxes to be cute and emotional, but the lyrics are quite serious. Draws fairly well.

The worldview is so beautiful Male 24 years old Vocaloid producer Japanese Focuses on cozy and gentle music, but the lyrics and content aren't (mostly about suicide). Still, there are many normal songs too! Good at using piano and dissonance. Likes light pink! Has characters called Iyowa Girls and a massive worldview called SLIP. Origin of name: Means the stomach hurts (I = stomach, Yowa = weak/hurts). In short, this person's stomach hurts a lot (recently improved a lot through diet management...). Shy and warm.

Bang Female 24 years old Vocaloid producer Japanese Many songs are somewhat dreamlike yet have that unique LonePi feel. Many songs have impure lyrics about fighting, suicide, etc. Says she drinks alcohol often since becoming an adult... Seems to have two younger brothers. All songs represent the relationships of characters in LonePi's original universe, #Lonely_note. Thinks objectively (says one shouldn't think emotionally).
