Column A is the monster you need to kill to get the Mitama. You then match up the monster name with the Age it's found in (it's location) to see which Mitama you get from it. Some monsters will drop different Mitama between chapters 1-5 (1st set) and chapters 6-9 (2nd set) Ex: Killing Manhunter (the first boss) in the Age of Grace during the first set of chapters gives the Mitama, Abe no Seimei (of the Spirit battle style). Note that some are "story related" and you get them the first time you beat an enemy while others have some % chance so you may have to kill multiple enemies to get a Mitama. Also, Mitamas are the souls of fallen slayers so the japanese names you see on that list are the Mitama themselves.
For anybody interested, here is a list of the Mitama names in alphabetical order. As said in the OP, this is copied from the link. Not trying to take credit for anything. Once people narrow the list down they can use the original link to see how to get the ones missing.:
