Han is the Third Rashō—basically the third of the top elite fighters under Raoh's command. He's best known for being the first real master of Hokuto Ryūken that Kenshiro actually has to fight in Asura, and he's got this unique thing going where his fists can generate intense wind currents that hit way harder than they look.
What makes Han a pretty significant character is that he's the one who drops the truth about Kenshiro's origins during their fight. It's a major moment—fans often note it as the turning point where Kenshiro starts understanding who he really is and where he came from.
