Heyo, this is a super strange question/request but I'm looking for a copy of a really old vn named Takahisa's Afterstory. It's a sequel to 11 eyes: Tsumi to Batsu to Aganai no no Shoujo. I reallllly want a copy of this game, but I can't find it anywhere. I don't care what language it's in or how much it costs. I just can't seem to find it anywhere. Anybody know where I can find it :((?
