Barestar

バレスター

A member of the Fourteen Lances who betrayed Ascheriit. Before being sent to the Emperor as one of the Lances, he was the son of a powerful merchant and the youngest of three brothers. Insecure and inept at handling business, he was chosen as an envoy to the Emperor instead, owing to his considerable physical prowess. He was a friend of Ascheriit and one of the few members of the 7 Heroes who understood what the brutality of their acts would bring upon them all. After becoming a hero, he appears to have been corrupted, possibly by guilt, and began living lavishly, consumed by anger and envy toward Glenn for not being granted war airship constructions. He secretly converted his fortress into a flying castle armed with Wischtech engines of destruction. Following Schtemwolech's death, he grew increasingly paranoid and fearful that even the slightest thing could be an attempt on his life. So paranoid was he that he sent his army to attack the city of Jullas-Abllas, accusing its citizens of supporting Koinzell. Ironically, his actions actually caused the citizens to support Koinzell and fight against his army. In the end, his own men betrayed him and abandoned him, a fact that finally drove him completely insane. When Koinzell caught up, Barestar believed they were back in the war at a point where Koinzell had saved him. He sadly asked Koinzell to help him return to his home and family. Seeing this, Koinzell killed him while he was in his stupor, as an act of pity. Barestar is currently the only one of the Seven Heroes for whom Ascheriit shows slight remorse for killing.
Of the Seven Deadly Sins, he represents Greed, as shown by his jealousy of Glenn's weapons and army, and his desire to have it all for himself.
