Erhard's Master

His real name was not mentioned, but he is the blacksmith who taught both Erhard and Tollynemiya.

Appearance
The Master is an elderly dog-type Demi-human, he is mentioned to have dog ears, though they seem to be quite different from Keel's.

Personality
He is a skirt-chasing, frivolous drunk. He is an irresponsible slacker who pushes all of the debt to his apprentices. He has wanderlust and loves to travel.

He is a womanizer and goes for any woman irrespective of race or age, even willing to betray his nation for a woman. He is also proud of his philanderer nature. He reminded both Filo and Naofumi of Motoyasu, so Naofumi has nicknamed him "Motoyasu #2."

Abilities
He was a skilled craftsman with an unparalleled talent for making katanas and swords. It is unclear if it is a natural talent or his race characteristics for his craftsmanship. The Master holds the rank of priest in the Q'Ten Lo's temples and is trained in the handling and purification of dangerous cursed weapons.

He was able to dodge Fohl's attack and withstand Atla's pressure point attack.

Background
He is a vagabond from Q'ten Lo and part of a legendary and prestigious family of blacksmiths of the nation. Somewhere along the line, he met Erhard, who fell in love with his work and became his apprentice. He advised Erhard that any blacksmith who specializes in any one weapon will hit a wall and that a blacksmith should try to keep an open mind and craft a variety of weapons.

He, along with most of his apprentices, travel along with the world and craft a variety of weapons, but most landed in trouble because of his massive debt and womanizing habits. This became the reason for most of his apprentices to leave him midway. Tollynemiya, on the other hand, had to leave because of his personal affairs.

He left Erhard with the note saying that Erhard is a certified blacksmith and had nothing left to be taught. Not long after, women and debt collectors encircled Erhard. One day, he was forcibly called back to Q'ten Lo after the rest of his family had died. He is responsible for crafting the specialized anti-Legendary Weapons based on his nation's ancient methods for suppressing the legendary weapons. He is mentioned to have serviced at least two generations of heavenly emperors.

Volume 13
He appeared briefly after Naofumi, Sadeena, and Raphtalia's successful infiltration of Q'ten Lo, and wasted no time flirting with the two women before Naofumi chases him off. He later returns during the group's attempt to knock out the land's isolation barrier, keeping their allies away, and helps by giving Naofumi and company powerful weapons.

When the barrier is finally taken down, Erhard has as a friendly reunion with his old master, before kidnapping him and dragging him off to the nearest forge to have him pay off the insurmountable debt that he owes his former apprentice.

Volume 14
The Master appeared briefly after the Hydra was subdued picking up the cursed weapon the monster was sealed inside of. Though initially wanting nothing to do with the blade upon request of Raphtalia the Master has eagerly taken the challenge of trying to purify the cursed blade. Unfortunately one out of earshot of a pretty woman the Master quickly goes back to being a pain in the rear end, to the point that Erhard asks Naofumi to take him out and drink him under the table.

On their way to the bar the pair encounter S'yne Lokk and a familiar-looking woman named Zelda who is looking for directions to the parade that was held earlier that day. After clearing up her confusion Zelda joins the trio as they enter the bar with the master wasting no time in flirting with the women and trying to take Naofumi out of the picture by buying him a bowl full of lukor fruits.

Unfortunately for the elderly blacksmith, Naofumi's intoxication immunity remains as strong as ever and instead the four of them participate in a card game before Naofumi tricks the Master into drinking some lukor juice. Later after the Master has sobered up he is introduced to Ren Amaki who requests to become his apprentice, the Master accepts on the condition that Ren helps him to escape later, and is horrified to witness Ren destroy one of his swords with his curse of Greed.

Relationships

 * Legendary Heroes
 * Naofumi Iwatani: Naofumi had a low opinion of Erhard's master from the moment he heard about him, immediately thinking about the old Motoyasu, and thus coining the nickname Motoyasu #2. His opinion dropped further when he actually met the man.
