Purification with only Soh and Yoshiro.
Only possible in Myoko Pass. The rest of the scenes always have villagers, mikoshi-bearers or the Carpenter.
I'm doing a Soh-only run and the bases are peaceful. I greatly prefer being alone with the Maiden.
If the game had just been these two, it would've felt far more dreamy and eerie. But it also would've been a very different kind of game.
