Köinzell is a master swordsman who, along with thirteen other heroes, was sent by the Szaalenden Empire to block an invasion of their enemy Wischtech. Along the way three died, four betrayed the others and seven defeated the traitors and returned as heroes. At least, that's what people believe. In reality the ‘Seven Heroes' were the real traitors, defeating the four true champions after the seven had fled the battle in cowardice. Köinzell has bided his time for twenty years, honing his skills and recovering from the brink of death so that he may avenge his fallen comrades. The time for vengeance has finally come and all who stand in his way shall be dismembered without hesitation, but it won't be easy as everyone believes the lies of the traitors. With all the soldiers in the land and the public against them, Köinzell and his ragtag allies may have to sacrifice everything if they are to prevail against the might of the entire nation.
Both Ubel Blatt and Superior are medievalish, fantasy action adventure series. Uble Blatt has larger quantity of explicit content compared to Superior (though it's still not as bad as it may seem at first), on the other hand Superior has a romantic subplot which Ubel Blatt seems to lack. Nonetheless, if you liked one of those two series, you might like the other one too.
Both Watashi no Ookami-san and Superior are about an end boss paired up wih a hero who was suppose to defeat him. Both of those are really hilarious. If you liked one, you just have to check the other one as well.
