Luke Ainsworth

Luke Ainsworth is the skilled blacksmith and talented swordsman who serves as one of the main protagonists (often considered the deuteragonist) in the anime The Sacred Blacksmith.

He is a highly renowned craftsman specializing in forging katanas (a rare and impressive style in the story's setting), and he wields a sword expertly himself. Luke has dark brown hair (often shown in a long, messy ponytail) and blue eyes, though his left eye is a glass prosthetic (fake/artificial, a result of past events tied to his backstory and abilities).

In terms of personality, he comes across as arrogant, insensitive, grumpy, and somewhat aloof or private—he tends to keep to himself, acts irresponsibly at times (like skipping important meetings), and can be rude or jerkish on the surface. However, beneath this exterior, he has a shy, timid side and shows genuine care (in his own way) toward those close to him, such as his elven assistant Lisa and eventually Cecily. This gives him classic tsundere traits (harsh exterior but softer interior).

He lives and works with Lisa, who helps in his forge and accompanies him, and his path crosses with knight Cecily Campbell after he repeatedly saves her using his unique skills and blades.
