Put it in the middle of a tribute edit, after the action clips and before the closing title card, then follow it with a short spoken farewell so the final moment belongs to the character, not the music.
Sobre este som
This 56-second piece from the Yu Yu Hakusho soundtrack pairs quiet piano with soft strings in a slow, unhurried flow. It leaves a listener feeling wistful and low, as if a goodbye is still hanging in the air, and it suits moments of loss, farewell and old friendship. It comes from the early-1990s anime about Yusuke Urameshi and his friends, a series that pairs supernatural battles with sacrifice and loyalty.
