Bulat was once a high-ranking Imperial Officer known as "100 Man-Slayer Bulat". He later decided to betray the Empire when his superior was framed for not giving in to the Prime Minister's agenda. Bulat became disgusted with the Empire that cared more for bribes, than merit regardless of how hard he worked. After leaving the Empire, he joined the Revolutionaries, and eventually Night Raid. Bulat's teigu is the Demon Armor: Incursio an Armor-type teigu that took on the form of a short sword with a chain link tassel in its sealed form. Once released, the user was enveloped in a full body armor.
