Hmm, Cirno and Mokou together have 36 assists but only 4 kills. I wonder who commited the rest 32.
It's also possible for both of them to get an assist from the same kill. And it's pretty frequent in games like Dota 2 (the game the artist seems to play a lot and refers to in multiple posts) for one or two carry players in a team to get the lion's share of kills while their teammates get the assists.
