Personality
When first introduced he is very arrogant, thinking that he is the most powerful, even though he earlier lost to Gazef. His personality changes drastically after having a run in with Shalltear. Having his confidence completely crushed and getting a feel of what true terror is like, his attitude changes to one where he is completely depressed, hinting at a suicidal tendency.

He eventually does a complete overhaul after meeting Climb and Sebastian. He changes to a much friendlier person that start to think that strength is more then simply being skilled with a sword.

Background
Originally a farmer, he was gifted with what could only be described as a god-given talent in the mastery of the sword. He has always believed himself to be the strongest fighter inside the Kingdom, having never lost a fight before he entered the grand tournament to decide the King's guard captain. He easily fought his way to the final where he faced off against Gazef Stronoff. A grand and close battle ensued between the two, but eventually he would taste his first defeat at the hand of Gazef.

His fame was shattered and his confidence as an unbeatable warrior took a hit. He then decided to do everything he could to become stronger, so he would truly become unbeatable. At the same time, in order to make a living he started working as a mercenary for the Death Spreading Brigade.

The Bloody Valkyrie Arc
He suffered a devastating defeat at the hand of Shalltear Bloodfallen when she attacked the hideout of the Death Spreading Brigade. His absolute confidence shattered by the immense difference of power between him and the vampire, he fled crying, escaping the massacre through an hidden exit.

The Men in the Kingdom Arc
Brain retreated to the capitol city of the Re-Estize Kingdom, in order to hide from Shalltear. Gazef finds Brain slumped on the side of a street and brings him back to his place of residence. Brain is still shaken by his momentous defeat and uses this time to recuperate. Whilst walking through the streets, Brain overhears a commotion and discovers Sebas Tian, as he incapacitates men who were attacking a young man. He follows Sebas, and Climb, into an alleyway where he sees Sebas release an extreme amount of Bloodlust and Killing Intent, directed at himself and Climb. This was Climb's requested training under Sebas. After the Bloodlust ends, Brain reveals himself and converses with Sebas and Climb before fighting off a group of assassins that were also following Sebas.

After defeating the assassins, Brain, Climb, and Sebas travel to the brothel where Tsuare was discovered. They attack the brothel and capture of the Six Arms, Succulent, and a member of Eight Hands, Cocco Doll of the slave trade. Following the battle, Brain goes back to rest as Gazef's house and they discuss the events and his defeat at the hands of Shalltear. Later, Brain is sent to partake in another raid on the Eight Hand's hideouts alongside Climb. He briefly talks with Gargaran of the Blue Rose before beginning the operation. When they begin, they have a scout infiltrate the compound they are to attack, who discovers that all of the remaining six arms are within the compound, along with a captured girl. As they are about to fall back, they meet Sebas, who came to rescue the girl, Tsuare.

With Sebas, the rogue, Brain, and Climb all infiltrate the back of the compound in order to rescue Tsuare while Sebas deals with the Six Arms. The trio use invisibility to infiltrate the compound and break Tsuare out of her cell. As they are escaping, they are ambushed by Zero, the leader of the Six Arms and are forced to fight. At the same time, they discover that the Tsuare they rescued from the cell was actually Succulent in disguise. In the encounter, the rogue and Climb are forced to fight Succulent while Brain fights with Zero. Climb and the rogue defeat Succulent and as the battle with Zero and Brain nears an end, Sebas appears and defeats Zero with ease. Brain, Climb, and the rogue all exit the building, only to witness a wall of fire off in the distance, which is thought to be another one of the hideouts being currently raided.

Quotes

 * (Facing Shalltear): "These foolish monsters that think they’re the strongest, they’re all the same. They think that humans are weak, that our bodies are fragile, our abilities nonexistent. But I will teach you how dangerous it is to underestimate us."
 * (To Gazef): "Stronoff! We can never reach the world of the truly powerful, no matter how hard we try. As long as we’re born human, this is the truth. In the end, we’re just children holding sticks. We’re playing with swords now, but we are still mere children pretending to be swordsmen."
 * (To Gazef): "Stronoff. Strength achieved from the sword really is garbage. It’s useless in front of true power."
