Meet Fujimori Kaname, a boy whose life was once saved by a knight amidst red flames and debris. That day changed him - his illusion of being all-powerful crumbled, but it wasn't despair that stayed with him. Instead, the image of the knight who rescued him inspired a vow: to become a knight who protects more people than anyone else.

Today, Kaname steps into Shiromiya Academy, a knight breeding ground. His first challenge? Joining the Shiromiya Squire Knights "Esquire", a test order for new student knights.

Kaname's journey is not just about training. It's about the companions he'll share it with: Elcia Harvence, with her striking golden hair and skillful swordplay; Kazama Akari, the spirited and impulsive girl from a modest background; Shidou Mana, the homely, marriage-ready daughter of a corporate giant; and his prodigious sister, Fujimori Yuu, who's a grade-skipping genius. Leading them all is Kuninaka Kaori, the calm and caring senior.

But there's a twist - Kaname realizes he's the only guy in the group. Amidst the confusion and a bit of worry, Kaname embarks on his knightly journey, stepping into a world of uncertainties and adventures.
