The art is very good but has no appeal. It's unique but somehow generic anime artstyle would be better. As for the writing. It's pretty good but not really that high. For the characters they're likeable but doesn't really stick. Overall above average.
I hope everyone at the party will inevitability dies due to being outnumbered then instead he kill each one of them then stole experience or gold or something after that he became so high level he basically become a warlord
