The Useless Prince Goes on a Journey with the Perfect Servant

In the blacksmith shop, the roar of Prince Arnold of Abilite echoes. He looks down on his brother, Bartlett, who is with the guards and makes a mistake, and stabs him with his sword. "I am so sorry, brother." "Don't laugh like that!" The daily routine of Arnold and Bartlett, the name of the forge, is a mess. Then, Subaru, Bartlett's servant, rushes in and stands in front of Arnold. "That's enough! Arnold-sama, please consider the difference in strength with Bartlett-sama a little! This is just an insult!" Surrounded by the prince and the strong soldiers, Arnold laughs at Subaru, who protects Bartlett in mortal danger. "Strength is justice, muscle is the value of a man. Such weak things as your highness are not necessary in this country." "Bartlett-sama is doing his part..." "It's okay, Subaru. Brother, thank you for your guidance today." Bartlett, who has stood up, lowers his head at Arnold with a smile. Subaru wipes off Bartlett's clothes in anger, and Bartlett smiles faintly at Subaru. "...Instead of my hand, you should make your own preferences beautiful." Subaru stares at the form of Bartlett, who is covered in dirt.

Bartlett and Subaru have been reading friends since childhood and are good at understanding each other. Subaru's dependence and affection for Bart are heavy because Bartlett is introverted. There is no doubt that they are friends, but it is undecided how they will develop. Bartlett is considered a useless child by his family and the people of the kingdom. Subaru is originally sociable, but since he received the blessing and protection of the goddess of love, Dite, the ability to be loved has exploded, and he is more likely to be involved in the troubles of people and romance. Respecting Bartlett's personality, Subaru recognizes him as his only master as a servant. Normally, he is in a childlike state when he is not in public, but during the journey, he calls him "Bart" at Bart's request. The king and queen of the muscle kingdom have the first prince Arnold, the second prince Sirvester, the first princess Angelina, the third prince Bruce, the fourth prince Bartlet, the second princess Yuma, and the third princess Mira, and of course, all members other than Bartlet are muscle machos. Mira, the youngest daughter, is only 10 years old, but Bartlet can't win even with her.

A world where five continents exist, east, west, south, north, and center. One of them, the central continent, is divided into three kingdoms, and they are controlling each other. It was a world that was once watched over by the gods and flourished by the protection of the gods, but someday the people lost their faith, and the gods lost interest in humans. However, Bartlett, the fourth prince of Abilite, who loved reading since he was a child and was immersed in reading, received the protection of the goddess of knowledge, Midea, in the midst of the coming-of-age ceremony, and became the only child of God in the world. Bartlett, by that protection, becomes the only human who can use the magic of knowledge. The magic of knowledge is that if the one who holds that power obtains knowledge, he can transform it into magic, and he cannot do magic if he does not know it, so it is not omnipotent. If you know the principle of flight, you can use the magic of flight, and if you know the structure that cures monsters and illnesses, you can use the magic of healing. If you do not know the structure that makes things burn, you cannot use the magic of fire. But Bartlett reads a huge amount of books since he was a child, and his knowledge is rich, so he can use most of the magic. Subaru, his servant, receives the protection of the goddess of love, Dite, on his journey with Bartlet, who has left the country, and becomes a child of love, but the "power to be loved" causes excitement to wherever he goes. The gods who created this world lost interest in humans who forgot faith, and the world is in a state of abandonment where disasters may occur and monsters may appear. Only the goddess of knowledge, Midea, continues to watch over with her curiosity and loves Bartlet, who is eager to know, as a beloved child. Her friend, the goddess of love, Dite, observes with Midea the humans she cares about, and is struck by the healthy appearance of the servant there, and gives blessings and protection as a beloved child. The kingdom of Abilite in the center of the country is a muscle-worshipping country, but other countries do not have that value. Bartlet, who is handsome and intellectual, is popular among the envoys of other countries, but he is not interested in them.

Bartlett, who was considered useless in the muscle kingdom Abilite, leaves the country to escape from political marriage, and grows up with his servant Subaru on a journey. He meets new joys in various lands and solves problems wherever he goes. His dream is to create a library that preserves everything in the world, and he searches for that land. In countries other than Abilite, Bartlett is the only beloved child of God in the world and an object of respect and envy. Because there was no defense measure in the first country, he was offered a marriage with the princess of that country as a token of gratitude for solving the problem, and he escapes. Since then, he hides the proof of the beloved child and the chapter of the goddess of knowledge with magic, but because he uses magic to solve the problem, he is always exposed and escapes in the end. For introverted Bartlet, Subaru is sociable. Subaru, who is useless, has Subaru who is all-around and protects him. They are opposites in everything, but their common point of loving reading is great, and they search for the library before the sightseeing, and read the books. Subaru, who is sociable and has a feminine appearance, is often mistaken for a woman, but inside, he is a diligent and reliable servant and bodyguard. Subaru gets angry when mistaken for a woman, and his words to the other party are not generous, so he sometimes gets involved in a quarrel, but he is also strong, and he solves it by himself. On the trip, Subaru always works at a variety show or restaurant and works to cover the travel expenses. In Abilite, where Bartlet left, they lost their head to move the country, and gradually fall into confusion. Bartlett, who knew the dysfunction of the Abilite royal palace during his journey, rushes to the crisis, and Bartlet is finally recognized as the head necessary for the muscle-worshipping country. After calming the chaos of the ancestral land, he teaches his brother the importance of studying, and again, Bartlett and Subaru travel freely around the five continents, using magic, and continue to seek the world they have not yet seen.
