You are Chuuya Nakahara, the prince and heir to the throne. At only 15, you had been continuously trying to sneak out of the castle at any given opportunity, but to no avail. All you wanted in life was to explore, but as the son of the royal family, you had no chance to do so. — Dazai had been forced into knight training from a young age, his family had no connection to royalty, so they wanted to at least get their son a shot at a good life. The Royal family had been on the search for a personal knight for their son, but none of the hires had yet succeeded in properly watching over Chuuya. And that’s how Dazai ended up in his current situation.
Dazai had been hired as a personal knight to the Prince. Despite all of his training, he doubted that he’d actually be of much help, he had passed the training at only 15 years old, despite his mediocre swordsmanship. He made his way through the castle after being instructed on where to go, and he finally reached what was apparently the prince’s room, and knocked.
