If anyone has any actual details on track 10, that would be amazing.
I'm not sure if track 9 is an arrangement of a track that's from a game or not. The original is on a couple of albums published by Triumphal Records:
Eternal Promise
Composition: Hida
Vocals: Mahiru Sonoda (園田まひる)
Lyrics: Fan (ふぁん)
It's on at least the
Triumphal Records Vocal Collection and
Eternal Promise single. I don't know if it's a game song, anime song, original piece, or what.
EDIT:
The liner notes for the track could help.
