Border Break Battle Record Book: Dai 2-ki Ace Border Saishuu Kessen
From Sega Retro
Just a note
I also saw this referred to as Border Break Union Battle Record Book. So it is possibly a book for Border Break Union, but as the book has literally no information on the internet from my searches, who really knows. JaxTH (talk) 11:22, 25 September 2021 (EDT)
