Kudo Eiko – HOPE ~ Not to be defeated, not to cry, and not to be daunted (Black Jack OVA 8 ED)

This song is from Black Jack OVA from the 90s. It is the ending theme songs for OVA 7-10 according to Anime News Network but I’m not sure if that is 100% correct. This is in Episode 8, which is titled “Thoughts For Green”. This is taken directly from that specific OVA.
