For context, there's been a total Kei-chan sweep at this year's Summer Comiket. With 135 doujin circles, she surpasses all of Azur Lane combined (114) and leaves a huge gap between herself and the rest of BA (for comparison, Rio comes in second at only 53 circles). As a result, she's been declared the new "Queen of Ariake", a title previously given to Kashima (Kancolle) back at Comiket 89 where she, much like Kei, dominated circle counts shortly after her reveal.
Btw someone on Twitter has compiled a circle count chart for every BA student at C108, so check out this tweet for more details.

Edit: Rephrasing for clarity.
