Farewell cruel world

I have found a way to get to Gensokyo, so I am leaving this place. When I have arrived, I'll send word on how I accomplished this feat for those who wish to follow me. Good bye.

I'm not sure I still want to go to Gensokyo if you get attacked randomly like that.
I just want to go for the magic and pretty girls.

That being said where can I find the portal?
