Kohaku

Kohaku is one of Mugen's founding members and later became its leader. After Tatsuya's death, Kohaku fell in despair and joined forces with Chanson to destroy Kuryu and SWORD. He returned to his old self after being dealt with by his former friends in Mugen.

Personality
Due to his lonely childhood, Kohaku became a daunting and aloof person. However, after meeting Tatsuya, he developed a jovial personality. He is the type to not show any weaknesses and will exhibit menace to those he considers a nuisance. On the contrary, Kohaku is a soft person towards his friends and always has their back. He cares deeply for Cobra and Yamato, and acts as their big brother. In reality, Kohaku is a fragile person deep inside. He is scared of being lonely again. When he realizes his friends was slowly drifting away from him, he became depressed and anxious. After Tatsuya's death, he was pushed to his limits, and would later seek revenge on Kuryu. During the container yard fight, he wasn't afraid to display ferocity to his friends in Mugen. Fortunately, Cobra, Yamato, and Tsukumo managed to bring him back to his senses. He would later become a companion of his former enemies, the Amamiya Brothers, and support SWORD on the battle against Kuryu.

Apperance
Kohaku is tall man with a well-built body, he is one of the tallest in the series. He has glaring eyes most of the time. His left eye is a prosthetic eye after injuring it during a fight when he was a teenager. He used to have short hair but later grow it. He is always seen wearing a dark long leather coat.

Fighting Prowess
Kohaku is arguably the strongest and best fighter before Takeru, with Masaki being the only one to keep up with him. Along a few individuals, his fighting prowess, strength, endurance, and technique are considered above the leaders of SWORD to a great extent. He has an incredible strength and endurance. His techniques are considered high-caliber. In addition to his strength, his strikes are exceptionally fast. He also has a great instinct. Kohaku can throw people with ease, and can even do it with one hand. Just like the Amamiya Brothers, he is a feared individual because of his fighting prowess

During the container yard fight, Tsukumo, Cobra, and Yamato fought Kohaku. In this fight, he was completely outnumbered yet he overwhelmed them and showed no sign of losing. Tsukumo, Cobra, and Yamato are one of the strongest fighters yet he endures their punches like it was nothing. Yamato, who is a tall and muscular man, is casually being thrown around by him. Cobra's techniques was of no use either, as Kohaku just overpowers Cobra. Tsukumo was also of no match to Kohaku. Even when the three attacked him together synchronously, he still overwhelmed them. Kohaku was fighting them ferociously, and wasn't pulling his punches. Fortunately, the three talked him out and managed to bring him back to his senses and realized he was wrong.
