>>115034There's also the case of Astel, who's pretty heavily implied to be an alien with his clothing, the bio mentioning him looking into space longingly, his robot mascot, and all the space themed visuals he has, yet it's not outright stated. A while back I sorted the Holos by origins, so I'll just copy that old post here for reference. I didn't know that Oga was supposed to be from another planet and not reverse-isekai'd from a fantasy world.

>They all pretty much fit into these 4 categories, but I can't seem to figure out what Botan and Polka would fit into, they don't seem to be based on any Japanese deities and would fall into Ordinary Humans if it wasn't for the animal motifs. Moona is also questionable as her bio makes her seem fairly normal but she's also been implied to be a goddess or from space, and Anya being a personified sword doesn't quite fit into any either. Ina and Amelia are both under ordinary humans since Ina didn't become a SAN drain until she got AO and Amelia's time travel is by using the watch, not an inate ability.>Sora and AZKi can arguably be grouped into sci-fi given their bios state they exist in the digital world. Miko also, since her bio says she's from the digital world originally.>The gamers are all fairly ordinary based on their bios, but the animal motifs lend them more to being minor deities who lost their powers since no one worships them anymore.>As for more direct connections, Choco, Shion, Ayame, and Rushia are all stated to be from the same demon academy.
