That chant orb arc was one of the best in all of Death March.
Although it was already mentioned, he got 10 points for each level he got. Also, he has learned Meteor as a skill when he used it at the start, and also levelled it up... it is a lot stronger now.
Eventually, he will find his style to fight and he wont need new skills anymore, so 3000ish sp is enough for him imo.
About the complaints, DM is a slice of life, not a shounen. The fights are in for just fun, but in reality this one is just an other one about cooking.
Oh, and he will definitely work more than 16hrs a day in the future.
So many ladies, huh.
