Ghost who has a cult following
I mean...she is a god. Joking aside, as one of the feral fans of this evil spirit, there are a couple reasons I choose to die on her hill. The first, yes, is its 'le funni me me' for the fans. But there's more than that. She is often the first nugget of obscure lore a fan wanting to get into the franchise comes upon. And with her unique design and placement in the series, she makes a strong impression on someone who sucks at bullethells but wants to hang out with the cool kids.
Speaking of, her design. Despite its many elements, its very appealing while not being overly complex, very easy to update. She is very self-assured and confident, as well as magically potent. As I mentioned in Yumeko's persona thread, confidence is a great trait in a villain. It makes them endearing, while also priming us for excitement when she is defeated. And yeah, she is sadistic and even petty compared to other characters, and that does make her stand out compared to other villains in the series. Her good endings also offer some potential for growth which would have been interesting to see. Either coming to accept her place in the world alongside the heroines, or deciding to pursue godhood.
A big reason why I want her back however, is...she fits so closely in the lore and the characters I care about. She is imprisoned on the Hakurei grounds, and has been for years. To the point she knows more of the Hakurei Shrine, its god and the orb than Reimu does. She taught Marisa how to use magic as her mentor. She appeared in every PC-98 game but one. Thousands of people saw Mima as the first alternative character in the series. In any other franchise, she would be a staple, closely tied to three of the main heroines, and a consistent figure in the background. But she isn't. And there isn't really an explanation why. Her only canonical mention since the switch to Windows, was her appearing on the cover of a manga she wasn't in. That's it.
Of the many early characters, only four made the cut to Windows, even if elements of others were recycled. There are plenty of PC-98 characters I would like to see reappear. Gengetsu and Mugetsu, Yumeko, Shinki. So while Mima is the most prominent 98 character to be ignored, its not like she's the exception to the rule. Still, none fit so deep in the lore as Mima. Despite being perhaps the most significant figure in the backstory of the two main heroines, and with plenty of potential for growth, she has almost no legacy in modern Touhou.
Some Mima fans seem convinced that we just have to hold onto hope. That if the memes and fan theories and false 'Mima is appearing in 2hu 69 guys!' continue, then eventually Zun will give in. They point to Flandre reappearing in the series after 17 years, or Ran coming back into the limelight. Ignoring the fact Flan is consistently one of the most popular characters in the series, and Ran was a personal request by Toby Fox whom Zun did a collab with. They hold up oblique references made by Akyuu and Reimu in manga to a past 'evil spirit' as a sign she is coming back, despite these being years old at this point. Others think Mima is the key to getting other PC-98 characters in. They think because Mima is more popular and prominent, she will be a perfect Trojan horse to get Elly, Shinki or Yumemi into the series again. I don't need to tell you how that's worked out.
I think its been so long Mima would not fit in modern Touhou. Not without a whole other game to reintroduce her. There's been 27 mainline Touhou games since her last appearance. There are fans today who weren't born when Mima was around. Personally, I have made peace with the fact Zun buried Mima in the backyard. My personal coda for Mima is after her last adventure she found peace. She reconciled with Reimu, embraced a crying Marisa and left for the afterlife. Because its a better sendoff than 'And she was never heard from again', regardless of how in-character that is for Reimu...
You do fan works
@Eulogous? I've been thinking of making a game series partly inspired by Touhou someday, when I'm less chewed up by life. Would you recommend making fangames as a buildup for that? Hearing Juuni and you talk about your favorite characters has been an energizing experience.
