Arguably Kasane Teto's most notable song. "Kasane Territory", also known as "It's Always Teto's Turn" was originally created on September 26th, 2008. The song is actually a parody of the Touhou OST song, "Beloved Tomboyish Girl" by ZUN. Not just that, it's also a parody of the Touhou fansong "It's Always Cirno's Turn" by Silver Forest. However, that fansong is a parody of another Touhou fansong, "Kero ⑨ Destiny" (also by Silver Forest). Therefore it's a parody of a parody. More information in this reupload.
