Apparently the 13.5TH Touhou game is going to be another Shanghai Alice+TASOFRO collaboration, marking yet another fighting game entry in the series. It appears to sport wildly different character graphics compared to SWR and IaMP, as well as even more changes to the fighter formula.
According to the teaser website, the focus of the game appears to deal with the themes of Faith covered in previous installments of the Touhou series. The small "world" within Gensokyo of humans is plagued with hardship and as such, they became pessimistic. People began to feel hopelessness when the imminence that the future would not change began to approach. Should also be of note that the phrase in brackets (ええじゃないか！) can be translated as "Isn't this great!" The transience of life became accepted and life itself changed to suit this pessimistic style of thinking. Thus, order became chaos. The more devout became aware of these changes, and sought to fix this. Thus, Faith was needed once more. Monks were able to establish temples, Taoists (?) who wished to leave behind their earthly ties and gain immortality and priestesses who wished to be reinstated to their rightful place...
These girls have decided. As such, it was time to declare "It's my turn!"
A charming battle using weaponry of Faith is about to begin.
EDIT: TouhouWiki-ites would probably know about this too. But I wanted to see everyone's thoughts on it.
EDIT 2: My actual take on the story, a more refined version of what I said here as I mentioned in #shrinemaiden:
18:19:52 (trancehime) 18:16:59 (Z-Virus) Someone translated what the voice said as "if nothing you do matters, that means it's okay to do anything". <-- That's the meaning behind the voice
18:20:01 (trancehime) The voice explicitly said ええじゃないか！ which means "Isn't that great!"
18:20:28 (trancehime) そうだ、何も変わらないのなら、何をしても良いんじゃないか？ <-- "If nothing you do changes anything (or matters), then isn't it okay to do anything?"
18:21:00 (trancehime) そうだ、もっと刹那的に生きれば良いんだ。 <-- "It's okay to live life as if you were living your last days." (aka, transience)
18:21:23 (trancehime) So the people started letting themselves go all out, and then everything became chaotic
18:21:51 (trancehime) The religious people took note of this and had to fix the situation and introduce order once again because that screws up a lot of things
18:22:15 (Z-Virus) and they used the chance to spread their religion.
18:22:46 (trancehime) Yes, they took over the people's hearts once more with their teachings
18:22:53 (trancehime) And thus, order was restored to an extent.
18:23:08 (trancehime) Once more, they needed to rehabilitate the gathering of faith
18:23:23 (trancehime) To do this, they set up a temple, and two important people were needed - a miko and a doushi
18:23:36 (trancehime) This sets the scene for the fightans
18:25:00 (trancehime) The kanji suggests Taoist.
18:25:09 (trancehime) But in the context of the story, I'm not actually entirely sure
