Pikamee mentioned in a recent stream that the average age of her viewers was 35. Given their popularity, one can only assume that the average age for a Hololive fan is even older. I dislike Mori, but part of the reason she's hostile to her fans is because she knows most of them are acting like maladjusted kids, when in reality they're pushing middle age (especially the big donors). What do you think the average age of your oshi's viewers are? Korone is mine, and I'd say her average is probably 40+.
