Linne Carlo better not count on Yuuta and the Mushou Iron Knights (translator's note: mushou means unparalleled). They are free mercenaries travelling from country to country, as it suits them. On the other hand, I do wonder if Yuuta can take that mecha with him. It's a national treasure, so the kingdom ought to be extremely loath to hand it over, even if they haven't got anyone capable of piloting it. That being said, they owe a whole lot to Yuuta. The usurper prince wasted a massive amount of money and assets, which might be hard to recover, yet the kingdom will need to fork over an astronomical reward to Mushou Iron Knights. I hope the foolish author bothers to address these issues.
