Websanemi’s act of aggression towards genya during episode 5 of the hashira training arc caught kamado tanjiro and the audience off guard.
Webas a member of the hashira, sanemi is an exceptionally skilled swordsman, the third best among the hashira, in fact.
According to kokushibō, sanemi.
Websanemi wields a standard nichirin sword and is a master of the wind breathing style, which focuses on mimicking the wind by creating destructive torrents.
I feel like no one talks how about how much sanemi lost.
