Hello there. As you might guess, I come from the song 'Devoid Beat.' ...You have quite a buildup of insult-tartar. Well, it won't come off, so there's no helping it.

Hello!! I came from the song 'Jinsei' (Life), which is also in Project SEKAI! Is it about time I started talking about the meaning of life?

Greetings. I come from the song 'Killer Spider.' Well, my days as a killer were decades ago... Hmm? How old am I now? ...You shouldn't ask a lady such things.

Hello, I came from 'Liar Dance.' Sometimes I'm mistaken for the version sung by Kasane Teto... but I'm the one sung by Hatsune Miku.

H-h-hello...! I-I'm... Chai... no, I'm Chai from 'Chitchai Watashi' (Tiny Me)! Oh, and, um... ...Yeah, that's right, sorry. ...Eh? Who am I talking to? ...Oh, right, you can't see them.

Hello. I'm the Professor... well, just like my name, I came from the song 'Hakase' (Professor). Like the name suggests, I messed up pretty badly in the past... Ahaha... wait, it's not a laughing matter.

Ahahaha! Hi, I'm Tetro! Huh? Read this? Let's see... 'I'm Tetro, from Tetrodotoxin'...? Tetrodotoxin is super poisonous, isn't it! ☆☆

Hello! ☆ I'm Aku! Apparently, I came from a song called 'Akumaburai' (Exorcism). That's exactly what I did before. Well, I don't really like that person, though.

Greetings. I am En. I came from the song 'Nidaime Enma' (Second Generation Enma). ...The name truly suits the person. I am a former Enma. ...Though I was removed from the throne.
