They both have a similar supernatural kind of setting. The major differences are that Tactics has more humor and Tousei is set up differently. Tousei is set up where there seems to be a bunch of one-shots that aren't really connected aside from having the same characters, but as you go further in the story you find that the chapters do lead to one main plot.
