This is dramatically different from the translation by Valhalla. To the point that even who he is referring to in his inner monologue seems to be opposites, with Valhalla's scanlation having him thinking about things such as the formula and efficiency of the magic circle that summoned him and this scanlation having him thinking about himself being wasteful and using too much mana. Totally different stories, it seems.
I think this one is less interesting than Valhalla's as it dumbs down the translation and doesn't make sense with the context of what people are saying and thinking. Undermines Yard's intelligence, too.
