Rival Schools OP/ED artist?

Hi, I’m a first-time poster with a question that’s been bugging me for… oh, just over three years now. A long time ago, I found the CD single for Rival Schools: United By Fate in a Japanese shop that had the opening and ending theme songs used in the PSX version of the game. However, my fluency in Japanese is lacking and I have no idea who the artist is or what the song titles are. Would anyone here happen to know what the songs are called and the name of the artist who sings them? I’d like to finally toss these into my collection without having to call them "Rival Schools OP" and "Rival Schools ED".

You don’t by any chance have a scan of the tracklist or the catalogue number for the CD on hand, do ye ^^?

I don’t know if you ever found out but the songs are sung by Isao Bitoh and are called:

Atsuki Koudou (opening) and Ashita no Yukue (ending)

its impossible to download the ost! its soo rare. dammit ur so lucky to find that ost.

I came across a Youtube video crediting "Isao Bito" for the vocal performance.
