Idk Gumi has been fairly cropping up only more apparent with recent releases. I see Luka more so for comparisons than anything else, I remember cringing at one friend in particular because she thought a HQ vocal (VY1 if i recall) sounded like Luka, or even more recently on tilt-six's AnonKanon song I saw one comment that thought the singer was Luka (like not a particular one, like both of them, they thought both was 1 singer).

Len comparisons are amusing though since they're often used against deeper sounding voices which could easily taken as "Len just sounds like a deep woman".
