Okay, I've been creating pages for some of the songs that we were missing. I would like to credit KemurianSeijinUS, who has a channel on YouTube dedicated to making music videos of Ultra Series songs with both English and Romaji subtitles.
Thanks to him, I was able to create the pages for Tatakae! Ultraman Leo, Hoshizora no Barado, and Aoi Kajitsu. I'd really appreciate some feedback on how I did creating those pages, cause it was a lot of work.
