Well Tigre-kun to Vanadi-chu is a 14 episode series of shorts linking to the original Madan no Ou to Vanadis. I'm actually surprised to say that i enjoyed these shorts may more than the original series. It pretty much cuts out the battles and such which they go into wayyyyy too much detail over and just provides some simple yet funny comedy, in which often they break the fourth wall and acknowledge they are actually in an anime. You have to see the original to get the jokes and stuff but if you have then i'd definitely say you should watch this.
