In the earlier chapters i was so interested in this manga because i thought it was rare (at least for me) to see the mc to be so dark and evil. Plus the way he tortured the princess was so great.
But now that's all there is to it. All these chapters felt like a filler to me and i didn't think i saw any development in the story. No side characters that really contribute to the story, no more princess, nothing really except the mc went here and there to get his revenge one after another.
Except the general that turned into a zombie, all the characters killed by the mc didn't make an impact after they're introduced.
Maybe i just put the expectations too high for a gore, ecchi, dark manga
