I do dislike the fact he gets a free evolution for nothing and the power she got out of nowhere.
they could at least make it an easy side quest.
System stories are not necessarily bad, and I enjoy them most of the time.
The information on how to evolve pets on its own can make a decent power and story premise even without a skillboard.
But too many freebies too fast could easily ruin the story's power scale.
and it makes no sense for a supposedly "low-tier" undead to be that strong (it is not like he got a myth-tier pet instantly )
but I will give it the benefit of the doubt at least.
Extra Edit after finishing the manga :
The premise of the manga is fine.
But there are too many asspulls for me to recommend it.
5/10.
It also seems to have been axed as chapter 44 is a poor ending at best.
It leaves off in the middle of a fight after introducing a new villain and re-introducing an earlier character who joins up with them.
( to take revenge on the MC despite MC technically being innocent and having nothing to do with the villains' downfall... )
The story has basically 2 story arcs and MC only got to evolve his zombie pet GF once.
Despite it being shown to have many more evolutions, so to me, it is clear that the story was set up to go on for longer.
The first story arc is a battle tournament to get into a good school.
And then it left of in the end of the 2nd school arc where MC goes to his new school as well as gets sent on a school mission.
After the mission, MC is starting a fighting with another classmate to get into the school ranking.
And then it ends in the middle of the fight.
