>Wait, step back. What's going on right now?
You idly step back for some reason.
At the moment, you are talking with Rinnosuke Morichika, owner of Kourindou and discussing a mysterious tear that apparently exists near the edge of Gensokyo. It's also near the cave Yukari Yakumo and yourself occupy when Yukari isn't napping like she currently is. She doesn't nap very often by the way.
On a grander scale, you are currently taking advantage of the time you have while Yukari Yakumo does not need to be occupied, less she get to work on killing people again, to try and fix some of the problems that have occured during her last rampage. You have already fixed the problem of the lack of a Hakurei Shrine Maiden, who you've left in capable hands, and while it is out of your hands to say she will once again lead in installing the spell card system and returning 'peace', you believe you've left her capable allies to push that to happen.
There is however, a greater problem you are currently dealing with. That is, a mysterious 'curse', that might not even be a proper curse, that seems to be working to cause havoc and destruction around Gensokyo. At that, you've found small 'leads' that the incident that ravaged Gensokyo long ago might have been the cause of another, and not simply the work of Yukari Yakumo like you believe.
