How guide books should be!
This book has a very nice chapter selection.

It has a section with info about the party members (stats, spells they learn, and the best, a detailed illustration), and sections for items and equipment, places, monsters, spells, mini-games/ sub-quests, everything.

There is even an extra chapter with details about the bonus dungeon.

I like it how many names are written in both Japanese and Roman characters (translated when needed), so you can see what the official English and/ or "Romanized" names for the items and places would be.

I think the only things this book keeps a secret are the identities of the bonus dungeon bosses, which is kind of a shame, but since everything else is included, they are forgiven.

This is a reminder of why I love Japanese guide books.
