She is a retro vtuber (well that much is obvious) but is very friendly, she likes to sing and dance too. She's friend with Yuno and Momoka and Rina and many other retro vtubers, and maybe even Lumi because Lumi raids into her very often these days on Lumi's longer streams.
One other notable thing about Dianko is she has a very cheap "play this game I recommend for at least 1 stream" redeem for retro games, only 5k points, so many of the games she plays are viewer recommended and it is a good opportunity if there is a game you like and want to see someone try.
