Sanemi is the Wind Hashira and Genya's older brother. Despite his prestigious standing, he's a hot-headed individual who lives for the thrill of fighting.
Kyojuro Rengoku was the Flame Hashira, a position previously held by his now-incompetent father Shinjuro. Even though he died at the end of his fight with Akaza, he managed to demonstrate his indomitable willpower.
Giyu was trained by Sakonji, who taught him how to master Water Breathing. He's come a long way in learning these techniques and has proven himself a strong combatant on several occasions.
