Six years have passed. Noah, now much older, walks forward as the maids and butlers bow to him, hoping for his safety. A carriage is waiting for him outside, as Zoe and Shirley walk behind him.
Noah Ararat, the twelve-year-old named the wise prince, is enjoying his breakfast when he notices one of his servants looking out the window, and asks her if there is a problem. Gigi answers that the line of people bringing him gifts still hasn't ended, even though it's been ten days. Noah answers that it's no big deal, and that it even lasted a week last year. Gigi is shocked, and the wise prince adds that he can't simply receive the presents and be done with it. The received items and the senders need to be recorded in detail, so it's a time-consuming task, but he's sure Evelyn will take care of it. Gigi is left in awe, but then the other servant sends her back to work.
Prince Noah, who is now twelve years old, has been recognized for fully mastering the magic sword Leviathan by direct imperial order. He is stationed at the Ministry of Military Affairs, which presides over the Imperial Army, and serving as its minister is his brother, the fourth prince, Henry Ararat.
Noah pays a visit to his brother to answer his call. Henry says that he wanted to know his opinion, and tells him that he got an imperial command to send Rimmeris to suppress a rebellion at the southern border. If the barbarians are shown any compassion, they get arrogant. So they are told to dispatch a regular army to show them their superior strength.
Rimmeris is the direct subordinate of the fourth prince, who, aside from his valor, is more than talented enough to lead an army, and is exceptional among the fourth prince's knights. Noah turns to him and asks him how many soldiers there truly are, leaving him shocked. Rimmeris is left shocked at the question and starts stuttering. Henry realizes something is wrong and asks Rimmeris what he is hiding.
Rimmeris falls to his knees and starts begging for forgiveness. Noah assures his brother that it's no big deal, and confirms with him that the Ministry of Military Affairs issues funding for the Imperial Forces based on the number of soldiers registered. He further adds that generals commonly register non-soldiers, like merchants and collaborators, and keep the excess funding for themselves.
Rimmeris apologizes and the fourth brother gets angry, but Noah stops him and tells Rimmeris to stop cowering. The wise prince adds that it's within a general's authority to add new soldiers. Normally it would be fine to register soldiers in name to serve as a deterrent. Henry agrees that showing an army of a hundred thousand is better, even if it's not true, and praises his brother for understanding these matters.
However, this time it's different. The emperor wants a swift victory, which is why Noah wants to know the limit of their manpower. Rimmeris honestly answers that the number is around two thousand, and Noah tells him to make sure to actually supply that many. He then asks for a pen and paper and writes something with it. Noah hands the letter to Rimmeris and tells him to take it to the Ministry of Military Affairs, and they'll supply him enough to cover two thousand more under miscellaneous expenses, and he can keep the excess. Rimmeris hesitates, and Noah tells him to take it and assures him that defeat will not be tolerated, leaving his brother impressed.
Meanwhile, the fourth prince teases his brother for not having any war experience. Noah is still at the first level, because it's the rule of the imperial family. Many royal babies die soon after birth. Officially it's attributed to an epidemic, but most of them are murdered by poison, by opposing powers. A prince is a valuable heir, and they aren't permitted to go to battle until adulthood or by imperial order. But Henry thinks that it's better for his brother to get some experience before he starts ruling his fief. Noah remains insistent on only going if he has the imperial order, and his brother assures him that he won't have much difficulty with the magic sword.
Suddenly, a kid runs into their carriage, begging for help. More kids run onto the road from an alley, being chased by some men. They catch the children as they beg for help, and the villagers watch. The children continue crying for help, and Noah finally steps out of his carriage to confront them. The man thinks he's some random brat and tells him to mind his own business.
Noah asks him about his registration and their business name, reminding them that unregistered slave trading is a crime under imperial law. The thugs get offended and pull out their weapons to attack him. Right then, Noah pulls out his magic sword and in an instant defeats the thugs. The villagers are all left in awe of his swordsmanship, and the kids wonder which house he belongs to.
Noah checks up on the kids, asking them if the men chasing them were the underground slave traders. One kid bursts into tears, telling him how they told him he'd be worth good money.
Right then, an old man interrupts them, greeting the wise prince. He adds that he lives off kids like these, and tries to introduce himself. But then he refuses to reveal his name, saying that he works for the first prince, Gilbert. Noah knows that the old man is threatening him with the first prince's backing. He takes a look around at the villagers, and the old man tells him to turn a blind eye to everything he just saw.
Noah asks his brother if he knows the old man, but Henry doesn't recognize him. The wise prince stares into the old man's eyes with a penetrating gaze, and the old man suddenly collapses. Noah then turns to the villagers, addressing them about how the old man falsely claimed to serve the first prince. He adds that others may be fooled, but he and his brother will not be fooled.
The villagers wonder who these two brothers are, and then someone from the crowd announces that he recognizes them. He adds that the little one is the songstress Alicia's patron, the wise prince.
Noah orders his soldiers to take the thugs away to Gilbert's estate, and explains that they claim to work for him, and orders the children to be taken to his mansion so he can hear their stories later. However, Noah couldn't kill the criminals if they actually work for Gilbert. But he couldn't just leave them be, because then the people would think he let underground slave trading happen. So it was best for him to call them out as fakes and let Gilbert handle it himself. Hearing this, Henry is amazed by his brother's wisdom.
Later at night, while having dinner, Noah receives a message from Gilbert thanking him for catching the thugs. Gilbert had them interrogated and found out they were actually falsely claiming to work for him. He wanted to send them to court, but they committed suicide.
