> Youmu: "It is not the most useful information, but at least we can narrow our search."
> Miko: "Indeed. I do even have one possible theory as to who Seiga is with, and thus where she may be hiding. The information we have is that Seiga has stolen the life force of a tree, a life force that is a tremendous amount of power. She is also currently far away from the Scarlet Devil Mansion, and she asked her mystery companion how 'it' feels. It also stands to reason that, if Seiga is hiding, she would not want to hide somewhere where she could be easily discovered. Now, again, this is only a theory, but it is possible that Seiga is sharing the power of the Saigyou Ayakashi's life force with her mystery companion, and was asking this companion how that power felt. I can think of one person that lives far away from the Scarlet Devil Mansion, in a place where random Gensokyo citizens are extremely unlikely to wander upon them intentionally or by accident, and who would be interested in obtaining a great power of botanical origin."
