I have no idea why the two vtubers on the Datsumou K's Frontier NekoNeko GT-R are both on the same car, in fact I'm a little confused why either is even on a car let alone for a second straight season given Nachoneko is fully independent and from what I can tell Tororo might be on the Rakuten payroll but just as a video game influencer that happens to be a vtuber rather than their IP.
