Helck
Helck is peak, 10/10, though I was hesitant to read it initially. Most reviews gave it an above average rating and bitch that the ending is series of Deus ex machina. Upon reading it however... what about the Deus ex machina's that were the series of last bosses at the end? If the bad guys got plot armour, why shouldn't the good have too? Why complain that magic that was foreshadowed nearly 50 chaps ago could solve the problem? (talking about that yggdrasil moss thing here).
People mistake grimderp as good too much these days. If they want a bittersweet or tragic ending, go read Hamitsu's works or 'SexuallyVictimedSaw man' or something.
