These save files contain:

Save 1 Hard mode Final Boss
Save 2 NG+
Save 3 100hrs gametime
Save 4 Dragon Secret Boss
Save 5 BnD Binder/Martha
Save 6 Legendary Job
Save 7 Halls of Tribulation
Save 8 Sidequests

You need to finish the requirements in saves 4-8 before you get the achievement. I saved right in front of the NPC/area. No buns used on 1-8.

To install, simply download and unzip it in your savegame folder which should be in %USERPROFILE% \Documents \My Games \Bravely_Default_II \Steam \<user-id> \Saved \SaveGames\. You can rename the files and change the number to change slot (from 1 to 9).
