This series is a** like there was no explanation about anything and the author jumped throught the plot and story development and made half-assed revenge-based character who goes around saying he dosent take dead weight while also going round simping over 50 useless random women.Also the story dosent make sense he didnt explain what the eruption was or what was happening or what stages where or who he was or what he was doing or what situation he was in but he just jumped into a boss fight in chapter one and then gets killed by his cheating gf who we have no background on like the author just completely skipped all the plot and character development like idk what a stage is or what the crystals are he was more focussed on making a powerfantasy wet dream of a manga where a badass mc goes around getting all the girls that was meant for 9 year olds with second grader syndrome.
