Why use Norwegian Krone? That doesn't help at all.
This is a scanlators joke, started by the "Norway scans" group. Whenever there was a sum of money mentioned in the manga, they've added translator's note saying how much that sum was in Norwegian Krone (and the joke is that for most of people this doesn't give any idea about how much this sum is - unlike the sum in Japan yens, which is pretty easy to translate into sum understandable by most of people: 100 yen = 1 USD).
Another joke was translating a "No way!" exclamation as "Norway!".
Other scanlator groups have picked this joke up, that's all.
