Teacher

Teacher (also translated as Master) is the narrator and main protagonist of Reincarnated as a Sword. He is a sentient magical sword that assists the story's deuteragonist, Fran.

Personality
Master is a father and guardian of sorts towards Fran. He takes care of and protects her while assisting her by providing his abilities and bonuses to Fran.

Master acts kind and well-mannered towards other people, except if they disrespect or try to hurt Fran.

Appearance
In sword form Master looks like a white longsword with three blue lines. Beneath the pale gold hilt is a sculpture of a courageous wolf and a decorative blue string. The handle is wound with a latticework of blue and white strings. Master gains the ability to change its shape and size later on.

Master also has the ability to create a clone of himself; at first, it takes his former human form, but as time passes, the clones take the form of a sword identical to his sword body.

Background
Before being reincarnated into a sword, he appeared to be a 30-year-old salaryman who enjoyed anime, manga, VRMMOs, and light novels. He had a friendly personality, enjoyed eating curry, and had some level of proficiency in cooking but had never dated before. At the start of the story, he is killed by an oblivious driver who was texting and driving.

Waking in this new world, he seems to have forgotten details on how he came to be and the circumstances on how he was reincarnated.

Volume One
A nameless sword awakens on a stone pedestal.

Fran
Fran was the only one who managed to hear Master's calls after being trapped in the ground. After pulling him free, she became registered to him as his wielder. In return, he saves her from her slave master by killing him and destroying the slave contract, setting her free. The two develop a master-apprentice bond that later grows into a father-daughter relationship. He is very protective of her and wants to help her accomplish her dream of becoming strong and evolving.

Master is in charge of cooking all of Fran's meals, often using materials from monsters they've slain. Fran appears to enjoy eating the curry that he cooks the most.

Trivia

 * Master appears to heavily resemble and/or be a reference to the Greatsword of Artorias, used by the character of the same name from the Dark Souls video game series. While he is roughly about the length of a longsword, when used by Fran, her small stature instead makes him resemble the likeness of a greatsword. He also sports a wolf motif and possesses magical properties much like the weapon he is based on, and later obtains a wolf familiar like Artorias did in his own story.
