The Hero Prince of a Weak Nation

The Kingdom of Urmila is surrounded by major powers and is ridiculed as a "weak nation." However, thanks to the efforts of one hero, the stigma is about to be lifted. The name of that hero is the second prince, Allen Urmila. The true identity of the prince who masters magic and has an overwhelming sense of battle is... “I want to leave the country and hang out with girls!” He was a useless prince whose motto was to live in self-deprecation! However, contrary to these wishes, they are forced into wars one after another... I don't want to go to war!
