Brain Unglaus

Brain Unglaus (ブレイン・アングラウス) is a warrior who turned mercenary after he lost to Gazef Stronoff in a grand tournament to determine the strongest warrior of the Re-Estize Kingdom.

Appearance
Brain Unglaus has brown eyes with blue hair and the appearance of a wild beast. He is equipped with chainmail, and wore a necklace and ring, which were infused with protection magic. His whole body is lean and his muscles are tough as steel and tempered through experience.

Personality
When first introduced he is very arrogant, thinking that he is the most powerful, even though he lost earlier 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 who starts to think that strength is more than 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. He went on a journey to improve himself, meeting various people such as Rigrit Bers Caurau. 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
When the hideout of the Death Spreading Brigade was being attacked, Brain confronted Shalltear Bloodfallen and tries to defeat her but suffered a devastating defeat, failing to even scratch her. His absolute confidence was shattered by the immense difference of power between him and the vampire, he fled crying, escaping the massacre through a hidden exit.

The Men in the Kingdom Arc
and The Men in the Kingdom II Arc Brain retreated to the capital 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. Brain is still shaken by his momentous defeat and uses his time to recuperate. Whilst walking through the streets, Brain overhears a commotion and discovers Sebas Tian, as he incapacitates the men, who were attacking a young boy. He follows Sebas and Climb, into an alleyway where he sees Sebas release an extreme amount of 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 Tuare was discovered. They attack the brothel and capture Succulent, one of the members of Six Arms, and a member of Eight Fingers, Cocco Doll, leader of the slave trade department. Following the battle, Brain goes back to rest at 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 Finger's hideouts alongside with Climb. He briefly talks with Gagaran 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're about to fall back, they meet Sebas, who came to rescue the girl, Tuare.

Brain, Lockmyer and Climb all infiltrate the back of the compound in order to rescue Tuare while Sebas deals with Six Arms. The trio use invisibility to infiltrate the compound and break Tuare 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 Tuare, they rescued from the cell was actually Succulent in disguise. In the encounter, Lockmyer and Climb are forced to fight Succulent while Brain fights with Zero. Climb and Lockmyer defeat Succulent and as the battle with Zero and Brain nears an end, Sebas appears and defeats Zero with ease. Brain, Climb, and Lockmyer 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.

Gazef Stronoff
Brain sees Gazef as his number one nemesis and rival due to his defeat at the hands of the Kingdom's Strongest Warrior. However, that all changed right after having his self confidence and willpower was crushed by Shalltear Bloodfallen. Unlike how they've met each other during their match together at the tournament, Brain confronted Gazef yet again, but this time he was in a pessimistic mood. Brain had almost prompted himself to even think of wanting to suicide before Gazef step in to stop him from thinking that way. Brain comes to later respect Gazef for his action and appreciates his kindness for helping him out in his time of need.

Shalltear Bloodfallen
Originally, Brain has once used to look down on Shalltear and thought of her as nothing more than a foolish and arrogant demon that overestimated her abilities. After Shalltear renders Brain's most powerful techniques completely useless with only her pinky finger alone, this also causes Brain's spirit as a warrior to become broken as well, realizing that she is an entity who cannot be defeated by him because he is just a human. Brain would then go on and flee from her with everything he has. During his escape to the Re-Estize Kingdom, Brain is unable to sleep soundly due to having nightmares about her following him until now.

After meeting Sebas and Climb, Brain has somehow manage to have gained back his lost confidence. Later on, Brain would come across Shalltear once again and already knows that he is no match against her. However, he was still determined on deciding to confront her again. Using his strongest abilities, Brain was able to at least manage to cut off a tip of the nail from Shalltear's pinky finger. This is tremendously joyful to Brain's pride that his entire life of training wasn't all for nothing.

Climb
After seeing Climb survived after being exposed to Sebas' killing intent despite being much weaker than him and finding out the reason he could stand up to a being whose strength is on par with Shalltear is because he wants to protect the Princess, Brain went through a drastic change in his personality, restored his confidence, and begin to care for Climb, helping him on many occasions.

Sebas Tian
Brain greatly admired Sebas' strength and believed him to be as strong as Shalltear. Brain also believed that even if he and Gazef were to fight Sebas together, they would still be outmatched.

Trivia

 * In the Web Novel, he becomes a vampire under Shalltear Bloodfallen.
 * He managed to chip off Shalltear's pinky finger nail using Fourfold Slash of Light, the second time they met.
 * According to Maruyama's tweets, Brain in the published books was homosexual. In fact, there was the setting where Brain was in love with Gazef, so that’s why he had no women in the bandit cave.

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."
