Ayakashi triangle seems to be similar to Bone collection, yokai story with romance and ecchi.
So there is a huge possibility that Bone collection will be canceled if Ayakashi triangle is successful.
I don't even think that Ayakashi Triangle needs to be a success for Bone Collection to be cancelled. If you think about what's likeling going to get cancelled next, when the next serialization round will most likely be and who the candidates for cancellation are by then, then Bones Collection is very far up there. Even though we don't know yet how well it will place.
I think probably nearly everyone here has the unanimous opinion that Guardian of the Witch is guaranteed to get cancelled. The other series to get cancelled is most likely either Agravity Boys or Mitama Security due to poor sales. I personally think Agravity Boys is more likely to get cancelled due to Mitama at least having high ToC placements. So there might still be many readers that enjoy it, but just don't buy the volumes, because it's just a gag manga.
Then, we can pretty much assume that the next serialization round will be sometime in August or September, because Burn the Witch is supposed to start in summer. So with GotW and either AB or Mitama gone, the next candidates for cancellation would probably be AB/Mitama (whoever survives) and the manga from the current newest batch. TPGW got a really good reception at least in the west and I would be very surprised if it didn't get a really good reception in Japan as well. So with that in mind, I think the most likely candidates for cancellation in August or September will be Moriking and Bone Collection, unless one or both of them do very well.
In Moriking's case at least, I can see the possibility that it could be very popular with elementary school kids in Japan. So I think it's hard to tell how well it will do in Japan. It could do extremely well, but also extremely bad. However Bones Collection so far imo really doesn't do anything that makes it stand out from the other manga we have in Jump or that Jump had in the past. So I'm inclined to say that it has a very high chance of being among the manga to get cancelled in August or September. Though this also depends on whether there will be 2 or 3 new series then. If it's only two, either Moriking or Bones Collection will probably survive, depending on who does better. If it's three new series, I could see both of them getting cancelled.
