>>3728345>So they gave loids real personalities in the game now? I'm not sure how to take this, honestly.Not really, the short explanation is that, in game, there are 5 bands/groups of OCs, and the game's story deals with their struggles and what not, and each of those groups has a 'Sekai' (virtual world/alternate dimension idk) spawned from their feelings and populated by the Cryptonloids, they get pulled into the Sekai once in a while and the loids help them with their issues.
So each Sekai has its own set of Vocaloids created and influenced by how the band members think of each character, some of the Vocaloids have closer connections to one specific band member even. For example, the idol group's Len is a cool princely idol, the theater troupe's Len is happy and naive, the group of introvert kids that makes music online has a shy and meek Len (

So all of them are the same Vocaloid character but at the same time they aren't, it's just people's interpretations of them, all equally valid since they don't really exist. It's actually one thing the game does really well, the Vocaloids aren't really full fledged characters but each version of them still has different quirks and banter with each other and the OCs, a nice solution to the whole "giving Vocaloids personalities" dilemma that has stopped them from making any kind of story with them before.
>I think Gumi has appeared in some Project Diva games and I'm pretty sure she doesn't belong to CryptonThere were a couple of Gumi songs in Project Mirai DX (3DS game), they only licensed her for that specific game though and it will likely never happen again. Projet Sekai has a ton of the more famous Vocaloid songs with non-Crypton-loids as well, including Gumi, IA, flower, and a few others.
