Disgaea 4: A Promise Revisited
Unfortunately, the number of guides available online for this game (Disgaea 4) was shockingly low. Finding good guides was a troublesome task as many of them were lacking in adequate amounts of information (presumably due to the fact that Disgaea 4 is so similar to its predecessors), and many didn't even include the details I wanted to know. What's more, the most comprehensive guide that I managed to find is actually pretty annoying to navigate due to the sheer amount of information that it holds.
But, none the less, this page contains links to all the guides that I found useful along the way.
