A bit of background: Monster Rancher is a fantasy pet raising and breeding simulator that came out in 1997 by Tecmo, based on their Horse Racing/Breeding simulator that came out year prior. A famous gimmick of the game was being able to put in any game or music CD into the PSX and the game would generate a monster from it.
Ultra Kaiju Monster Rancher came out in 2022, and is a Cross-over game between Ultraman and Monster Rancher, a collaboration between BandaiNamco and KoeiTecmo, where you can raise Kaiju from the Ultraman universe, though many characters and two monsters from the MR games make appearances.
The game has an amazing soundtrack and after many unanswered messages to BandaiNamco/KoeiTecmo to release something official, a manual one was created. I hope you enjoy it :)
