senyuu is pretty cool,the plot is pretty much your standard fantasy anime,a demon king summon an army of monster to invade the world and the hero has to defeat him and yadda yadda... but the things it's totaly bonker,hilarious and random,the hero gets abused by pretty much everyone and spends very little time on air,he is a followed by a soldier who spends all his time pestering and annoying him,the demon king is actualy an harmless loli who actualy summoned the monster by mistake (she wanted to make popcorn you see) she summoned 12 demons (all with the names of a month) and they too are another layer of stupid and each episode ends with some new character introduced,a cliffhanger or a plot twist... each episode is only 4 minute long so it takes less time going through the currently released 18 episode than your average shonen fight... apparently it was some sort of web manga before being made into an anime which is why the episode are so short
(this is the web manga)
