I was reincarnated as the Emperor's youngest son... but he's my best friend?!
This is the Holy Empire of Raphaer. A land blessed by God with fertile soil in all seasons, where every year brings a bumper crop and no citizen suffers from hunger. In the Holy Empire of Raphaer, even young commoners are literate, magic and swordsmanship exist, and numerous races such as elves, beastmen, and spirits live in harmony with humans. The citizens, regardless of noble or commoner status, enjoy prosperity under the shadow of Perdion, the deep-rooted imperial family. Of course, the amount and method of prosperity enjoyed vary from person to person. However, one thing is certain. **No one even dares to attempt to defy the Perdion family.** The Perdion imperial family stands firm as a great pillar of the Holy Empire of Raphaer, based on overwhelming power, position, and public sentiment that does not waver due to the constant abundance. ------------------------------------------- And then there is the Emperor of the Raphaer Empire. His name is Helbern Perdion. A superhuman man born with talents in various fields, such as magic based on vast mana and swordsmanship wrapped in agile and strong sword energy, which most ordinary people cannot use at all. His swordsmanship surpasses that of a Sword Master, and his magic is said to be at least Class 8 in a magic rating system where Class 9 is the maximum... Perhaps because he ascended to the throne after losing his parents—the former Emperor and Empress—at an early age, he has been ruling the Raphaer Empire for decades, receiving the cheers and gratitude of his people through his long experience. ------------------------------------------- **And in this empire, a few years ago, a funeral was held for that guy who was considered the greatest genius of the empire, a talent that might not be born again even after a hundred years.** During his lifetime, he was the closest friend of the current Emperor, Helbern. They bickered often, and even Helbern, who was so perfect it was a fault, could finally feel like a human being, laughing like a fool and sharing a drink with him without being bound by work or reputation. At the same time, he was the teacher of Helbern's son, Crown Prince Arsen. He often got annoyed and bickered while teaching, but he felt quite good seeing his disciple grow day by day. On the day he died, on that day when record-breaking heavy rain poured down as if a hole had opened in the clear sky where natural disasters never occurred due to God's blessing. Those who witnessed the expressions of Emperor Helbern and Crown Prince Arsen as they stared at his coffin being transported with wide eyes could never dare to open their mouths again. ------------------------------------------- However. A few years after his death, in this land that has now returned to the Raphaer Empire of old, once again, a great blessing occurred that filled one side of the newspaper. **The youngest Prince... the youngest Prince has been born!!** It was the birth of the late-born youngest son, the second Prince, of Emperor Helbern, who was famous for being a fool for his children. The bells of blessing rang so loudly they felt like they would tear eardrums. Even years after the youngest was born, the corners of the mouths of Helbern Perdion, the Emperor, and Arsen Perdion, the Crown Prince and the youngest Prince's older brother, showed no sign of coming down. The sight of a 41-year-old man with a youthful face and a large build, along with a 19-year-old brother, holding onto a little kid around 4 years old and not letting go. All three had black hair, and although the youngest had heterochromia with one eye being black, they all had the same brilliant red eyes, making them look like a very harmonious family at a glance. However. That was the problem. **I can absolutely never tell this doting father and son, who cherish me so much just because I'm the youngest son and brother, that I am the reincarnation of their friend and teacher who kept his memories!!** That's right. The youngest Prince, who is called the little sun of the empire just by his cute existence. In other words, Guest Perdion!! **Was the reincarnation of that guy who was the greatest genius in the empire...!!**
