Basically, Bloombolt is entirely a construction of a few extremely dedicated Koharufags who do all their own art and fics and then crop Goh out of screencaps to put Ash and Koharu alone or hyper-emphasize the, like, 4 interactions they had all series. Couple that with a sudden rise in AshxKoharu NSFW hitting Pixiv, and I'm almost certain the latter has carried the ship to that spot in views. No doubt Koharu will fall off over the next 6 months if anyone runs the numbers again then.
