Help me identify a series of anime, video game OSTs, songs, and almost lyricless tracks from these animation videos please

I was browsing through YouTube videos that have been salvaged - meaning they were saved before that user was either terminated or they closed their YT account.

One day, I stumbled upon this (make sure to click the icon on the top right of the video player to see the full list of videos):

https://archive.org/details/mmd-sto...id+Story+Vocaloid+DRAMA[PART+6_LAST+PART].mp4

If you can help me identify the names of all the songs and BGM tracks used in all these videos, please do, I have a serious migraine after finally seeking my long lost gold nugget: Sara's Theme/Fate - Breath Of Fire 1

I especially need to know the name of the song and version type used during the sequence where the three grieve over Neru's death. Again, AHA music, Siri, Shazam, and SoundCloud can only aid in so much. I even tested them on a track like In The Darkness Lies OC Remix - Banjo Kazooie, and they were all unable to identify the track. So, this is where human sleuthing is needed.

These are all going to help me learn how these types of tracks are utilized in these types of scenarios.

Extra note: Naruto is both an anime and a video game franchise, so this is why I added both video game and anime BGM.

UPDATE:

In The Darkness Lies OC Remix - Banjo Kazooie
Speranzaria - e-spaces.com (used in many sad MapleStory Short Stories)
and now, Fate, AKA, Sara's Theme - Breath Of Fire 1

These three tracks are what convince me otherwise that these "unknown" tracks are still out there somewhere waiting to be discovered.
