>The top agencies remain Hololive, NIJISANJI, and VShojo, whose streamers collectively accounted for about 48.1% of the total Airtime. Over the past three months, Hours Watched for Hololive streamers rose by 8.8%, while HW for NIJISANJI streamers increased by 1.9%. In contrast, VShojo saw a remarkable increase of 10.5% in HW, largely thanks to ironmouse, who held a super successful subathon in September and set a record for the number of paid subscriptions.

Chart in OP still has ironmouse in Vshojo which means her viewership share only got them up to 3.2 %. Its no wonder everyone else including hololive is eclipsed by independents; their methodology counts EVERY "vtuber" hours watched including 1views and probably defunct channels like Senzawa.
