The Thief (The Invincible Soldier)

"I never expected a farewell like this"

- the Thief, after killing the mercenary

The main character in the music video "The Invincible Soldier" by Jun Maeda, an anime and video game soundtrack composer and singer Nagi Yanagi, is an unnamed female thief living either in medieval Europe or a fantasy world very similar to medieval Europe. The thief is assumed to be an orphan, and was forced to join a gang of thieves since childhood, stealing and killing in order survive. The thief was often beaten by the leader of the gang (described in the music as "aniki" or older brother- as gang leaders are often referred to in Japan), if she refused to give him a large cut of her loot.

One day, a traveling soldier, likely a mercenary with a reputation for being "invincible" in battle encounters the gang and kills all of them, save for the female thief, who he believes to be a victim. Telling him she had nowhere to go, the Thief joins the "Invincible Soldier", wandering the world with him and becoming his apprentice. Her original intent was to learn as much as she could about combat, then leave and possibly kill the mercenary, but in time, the Thief fell in love with the "Invincible Soldier", and stayed with him until her old habits caught up with her and she attempted to steal a sword from a blacksmith's shop. The blacksmith spotted the thief's actions, and she was forced to kill him.

The thief expected to be killed by the "Invincible Soldier" before she could react, but instead, he challenged her to a duel. The two of them fought, and the Thief killed the mercenary in battle. After she killed him, she realized he was fighting with his non-dominant hand, intentionally allowing her a chance to defeat him. After which, the Thief looks down on the soldier's fallen body and sadly reflects on her actions in life, saying "perhaps things would have been better if we had met some other way".
