This is a topic I saw get brought up on another forum for a different series, but when I saw it there, it was so thought-provoking that I decided I wanted to see how Touhou fans would react when faced with this question, however uncomfortable or painful.
Most of us don't have a very wide net of people in real life who are into Touhou like we are. We might have a few friends who are into it, but in general, we're left to pursue our Touhou interests online, uploading replays and posting cosplay photos and writing up Danmakufu scripts, or whatever. We have fun and contribute to our fandoms online, pursuing our enjoyment in the ways we see fit.
But what happens if something goes wrong, and you die? Then it just ends. If your Touhou merchandise, from figurines to game CDs to wall scrolls lasted 'till the end of days, then we might consider those to be fitting tombstones to us. If we could be buried with our hard-earned collection, then wouldn't that be great? Or would you rather it be split up, distributed, or maybe donated to a toy or art museum, maybe passed on to younger siblings or children? Or depending on the circumstances of your death, what if it's sold to pay hospital bills, or the cost of burial? What would you like to keep regardless, maybe have buried with you?
What about your friends in the fandom? If your account just stops posting, will your friends have your phone number or address in order to contact your family and ask if something happened? Will they even know? I have heard that this problem confronted the TH-P community a few months ago-- one of their writers died in a car accident, and his mother was able to get online on his computer and inform his friends, as I heard it. Do you have something like that in place for you?
It's a difficult series of questions, but it's one I think we'll all have to confront, because unless something else happens between now and then, this is what will happen to all of us eventually; we'll leave behind an idle account on a forum or two, and a room filled with merchandise waiting for us to come back and play with them. Frozen in time.
My apologies if this somehow makes people feel uncomfortable or brings up bad memories, but I do think the question is worth asking.
