Can anyone help me find "Takegami: Guardian of Darkness" online?

[LtTora]

I had, (not had, past tense) a digital copy of Takegami: Guardian of Darkness and it somehow got deleted and I have been trying to find some way to get (if possible) a hard copy from an online auction like Ebay or something but in Japan.

Or if anyone knows of a website where it is possible to find a digital copy of the full soundtrack?

I know I am probably grasping at straws here but I have to at least try.

Again, I am not asking for anyone to share their copy with me, just if you could advise me about where to find a hard copy or digital somewhere? Thank you!
