@nachtness it's more than 500 chapters long and it's a 4-koma; I think it's meant to be read like you read a newspaper and not like how you read a good manga with a story. People probably skip chapters a lot.
More than half of the readers are going to end up angry no matter who wins haha. Then people are going to start shitting on it and it'll turn into nisekoi.
@Kaarme A fantasy world gives us a lot of leeway. The key point might not even be metal manufacturing, but rather the availability of high-purity ores and deposits. If the land was once hit by a huge iron meteor and now has huge quantities of very pure iron, that would make this possible.
