Aosa

Aosa is fair-skinned man of above-average height. He has sharp, blue eyes, and short, brown hair combed to the side. He wears blue robes and round, frameless glasses.

When the daimyō restricted the medical treatment during an epidemic, seeking to financially profit off it, Aosa secretly developed a cheaper and more effective treatment for the population. However, the daimyō discovered this and sent his elite assassins to eliminate him and his fellow students. Before being forced into hiding, Aosa gave enough money to his student for them to make the journey to his close acquaintances abroad.
