There are a few reasons why this series isn’t that good:
1. Repeats the exact same joke with little to no changes. The girl never makes progress
2. There isn’t any real character development.
3. No social bonding. We don’t know why the girl loves this orc who sits around and gives nothing back. She is throwing things at a brick wall.
4. No stakes. We have no reason to care about the MC, her party or her orc, or even the Mcguffins. They don’t achieve anything nor would their deaths change the story.
In short the first few chapters are enjoyable, but stagnant repetition is boring. Don’t waste your time on this either for the ecchi or the story. And future authors… please make sure your characters grow or change, or at least give us a reason to care for them.
