Not just any iteration of Gensokyo though, but the one riddled with puppets! Ch 5 - 100%

Shifting and Fluctuating World VersonGensokyo by WallabeeJump reviews
Othinus throws our main character into Gensokyo. Well, at least the locals fight fair instead of using hitscan explosions. What defines a main character? The poverty, the free loaders, the black hair or the name with religious connotations? The power to float above reality or the power to bring down to reality? A story of self doubt, random references and multiple retries.
