I'm a big fan of Holostars and have been for quite some time now. I've heard things about how Yagoo is personally invested in them, and some people calling Holostars "Yagoo's pet project." I've also seen that he's drawn fanart of them, I think I had heard he bought Rikka a guitar, and has even collabed with them at some point, I believe Roberu has mentioned he played Mario Kart with him at one point. Is there validity to any of this? I think it's really nice that he is if it's true, and I think it's safe to assume they're valued and wanted by him in the company.
