Funny Chapter,really. I don't know a single antagonist in the whole shonen genre who got stomped that badly by the good guys as the Demon King does. The price for the poorest villain ever gooooooes to......the Demon King. Even Hao Asakura from Shaman King was a better antagonist and he got bitch slapped by the love train and the ghost of his mother in the end.
Enough rant about the DK. Chapter itself was...okay. Not good,not bad,average. Better stuff can't come from this manga anymore and I hope there's no chance that Nakaba put the SD as fodder in the endfight. Considering that even one of her grace can solo the DK it would be a shame if the sins can beat her.
