>>6385262Whether to your taste or not, Risu's performances and voices surely aren't "generic".
I think the chart's placing Risu in her own little spot is probably (half-joking) appreciation for her dual voices and the sweetness of each. She's not going to sign a record deal, or anything. And AZKi must be a better technical performer. But Risu gives something special and different to those able to enjoy it.
