Obanai Iguro

Obanai Iguro is the Serpent Hashira. He is very cold towards Tanjiro because he talks to Mitsuri. Obanai also has a snake named Kaburamaru, who apparently helped him escape his execution when he was a kid. Obanai also has two different eye colors, one teal eye, and one yellow eye. He is 21 years old and is friends with Sanemi, the Wind Hashira. (This takes place during the Hashira Training Arc)
