Touhou 10.5: Scarlet Weather Rhapsody is the Touhou game where we get to see Mokou and Kaguya’s full power of immortality. It’s also a platformer shooter Touhou game, so it has a bunch more bullet patterns than previous Touhou games.
As always with Touhou music, if you like Touhou and Touhou music, I highly recommend checking out ZUN’s other works! They’re all linked on the Touhou Wiki .
For those who want to play Touhou 10.5: Scarlet Weather Rhapsody , there’s a translation patch for it. The translations aren’t as polished as the final Touhou games (more like Touhou 8.5 or Touhou 9.5), but they’re still a great way to enjoy Touhou 10.5!
For those who want to read about Touhou, there’s a Touhou Wiki that has character profiles, information on Touhou lore and the like. There are also fan-made Touhou Wikis that have translations of various Touhou doujin works. Touhou Wiki also has a list of Touhou music, so if you want to find one song in particular (including Touhou 10.5 songs), there’s a good chance it should be listed on the Touhou Wiki Music page .
