Happy New year everyone!
After watching and reading some content recently, I have started to become very curious about the subject of rivalries between Touhou and other series. (This does not deny the fact I am quite happy the Touhou fandom is actually friends with other communities as well, probably the best example coming to my mind right now being the TF2 community) Especially since for as long as I have been in Touhou community (entered my third year), I have not seen anything serious going on.
I have heard a lot about the times when some parts of the Touhou and Undertale fandoms clashed, and actually seen some of those in comments for old videos (they really feel like a time capsule reflecting the times).
But there are some old, perhaps gone rivalries I have heard about, yet know too little about what happened, and would like to learn more about those times. First one I would like to ask about was apparently between Touhou and Kantai Collection (Kancolle) fans. From the very little I know, Kancolle was nicknamed something like "the Touhou killer/the series that will kill Touhou"? I would like to know what actually happened at the time, how things developed, and what is current state of the relation between the two fandoms.
The second thing I was going to ask about, despite possibly not being a fandom rivalry, but really got my attention as I was writing this, is regards to a Twitter post (confirmed to be fake news - I will cover that in the following days). Apparently, Touhou has been replaced this year from the Comiket introduction booklet by Blue Archive, and that this is the only other time it happened was in 2007 (which again, was confirmed to be false). Does anyone have more context on this issue? I don't really know what is going on, how it ended up like this, and if there are any possible consequences if fandoms start acting up again. From the way that tweet was framed, it implies that Touhou was used for the booklet for a long time, and this year it was for the first time replaced by another series after a decade and a half?
I would like to learn more about the topic, especially about the relation with all the series that through time were framed as "the series that will kill/overthrow Touhou". But to me, one thing is clear: you can't kill Touhou. No matter if is is no longer the most popula series or ends up getting outshined by some new sparkly thing, Touhou will continue to exist. Therefore, I would add it as a third thing that would survive a nuclear fallout, along with cockroaches and rats.
