YMMV / Marry Grave

• Complete Monster: Markov is the Gorgon King who invaded the Dwarf Kingdom by petrifying most of the people inside so that he could put them in his collection of statues. In the past, he was a stepfather of Riseman Sawyer's guardian, Dante, who uses him as a puppet for slaughtering most of the soldiers while lying about what happened to Dante's parents. After Dante found out the truth, Markov killed Dante's parents during his murdering spree just for the sake of his amusement, and when Dante re-settles his score with Markov in the present day, the latter simply petrifies Dante.
• Too Good to Last: The manga was widely praised, regularly had color pages in Weekly Shonen Sunday, and seemed on its way to becoming a hit, but it was ultimately cancelled after 52 chapters due to low volume sales.
