It was auctioned a few days ago and I kinda regret I didn't place a bid on it. Didn't add it because there's basically no info on how it was released (probably some omake disc)
紅蓮天衝-修羅- LIMITED SOUND DISC
The scan refers to "願いながら…" (composed by
Hidehiko Enomoto) as OP and "時の旅人" (composed by
PYON-MO) as ED which is exactly the opposite of what BANDiT info and Youtube videos say.
Notably though, this may be PYON-MO's only work (under this alias) outside of Studio e.go!
