>>103332371Look I like IRyS and I think she's technically the more versatile singer, but IRyS is somehow debuffed by, I don't know, a "reputation" for JP archived karaokes, such that even when she does unarchived ones, it's not as big a buff as it should be.
Back in 2023 when Mumei was about as active as IRyS was, her regular karaokes were regularly in the 15k-20k ballpark, plus a birthday one that hit 36k. In terms of both peak and average karaoke ccv, within months of her debut if not immediately, she was 2nd behind Gura, and remained so until the end.
Also I don't recall whether IRyS was stronger than mid-tier first year Fauna, beyond her record breaking 2.0 redebut, but by 2024 Fauna and Biboo were competing for 2nd highest average ccv in EN behind Gura and hit 10k more often than not.
Remains to be seen if IRyS can incline to that level, though the engine bots/raid plague that's hit practically everyone by now is making it hard to tell what the actual state of things are.
