Transmigrate to Mount & Blade: From the Start, I Beat Up the Protagonist and Steal His System

On the first day after Yasuo transmigrates to Calradia, he is still a mere supporting character when his half-brother, blessed with a protagonist's plot armor, frames him before he can even leave the castle. His father is killed on the spot, and Yasuo inadvertently takes his younger brother's Mount & Blade System. He beats the protagonist senseless and escapes with his life.

Compressed rations, snow sleds, plate armor, and cavalry: Yasuo needs every one of them!

Territory and prestige are no problem for him!

The lowly supporting character's rise begins, and in time he will take the protagonist's place. Can Yasuo defy the prophecy that the dragon slayer will become a dragon himself?

The tangled romances of two generations, the shifting alliances among six kingdoms, and Yasuo's diligent efforts every single day in Calradia!

No brainless antics or filler. I'll do my best to bring you a vivid, lifelike medieval Calradia.
