Eiyuden Chronicle: Hundred Heroes - All Enemy Locations for 'Know Thy Enemy, Know Thyself' Achievement

Like any classic RPG, Eiyuden Chronicle: Hundred Heroes has an enemy bestiary. It can be found in the library in your base.

While I do note down in our 100% walkthrough where to find each enemy as you play through the game, this list is for reference in case you are missing one and find to find it more quickly. It's pretty straightfoward. Check the list below and compare it to your own game.

Eiyuden Chronicle: Hundred Heroes - Enemy List

Note: This list is the same as the one found in the library in your base. However, I adjusted the note about enemy location in some places, as the in-game listing sometimes uses the wrong name, or is flat-out incorrect.
