Does anyone know how to unlock this character, I don't really want to purchase the bell weapon on its own?

Hello! I'm working on our "wiki" of related games at https://reddit.com/r/survivorslikes and I was hoping a more experienced player might be able to help me with some questions about Return to Abysss 1. Are there any "vendors" inside a run? 2. Is there a "bestiary" unlockable in game? 3. Are there any "secrets"? I was also wondering if anyone knew if the English localization is currently being updated? Thanks so much! Looking forward to learning more!...

In the 4th zone there is a book or something just above and the left of start in the black wall i cant find a way to get it is it a known bug or is something wrong with my game?
