Bardroy

Bardroy (バルドロイ, Barudoroi?), usually referred to as Bard, is the household cook of American descent. Bard gruffly treats everything as though it's a military exercise, often referring to troops, enemies, and weaponry when he goes off into one of his many long-winded speeches about what it truly means to appreciate the culinary arts. He rarely produces anything edible as he uses weaponry such as a series of flamethrowers, each more extravagant than the last to cook and believes cooking is an art requiring explosions. Sebastian believes anything he creates is made up of charcoal and carcinogens. It's unknown if the food he produces is actually edible. 

Bardroy pursues cooking to learn how to slow down, as he states cooking takes patience to master.He used to be an English soldier whose entire platoon was wiped out, leaving him to be the only survivor. While terrible at cooking, he is shown to be capable of taking advantage of his surroundings, such as using fine quality flour to create a dust explosion.

At the anime's conclusion, it is unknown whether he is alive or dead, although it is noted he was breathing before he collapsed.
