Kanae Kocho (胡こ蝶ちょう カナエ Kochō Kanae?) was a Demon Slayer and the late Flower Hashira (花はな柱ばしら Hana Bashira?). She was slain several years prior to the present story. She is also the biological older sister of Shinobu Kocho and the adoptive older sister of Kanao Tsuyuri.
Kanae was a girl of a slender build, much like her younger sister, who was rather tall for her age and had notably red lips in contrast to her pale complexion. She had long, straight, black hair that reached just below her waist, worn down with two shorter clumps over her shoulders, and arched, ear-length bangs on either side of her face. Her eyes were a pale violet and slanted towards the sides of her face, bright and bug-like, with many notable white sparkles reflecting light off of them.
Kanae wore a purple-tinted version of the standard Demon Slayer uniform, as well as a piece of butterfly patterned fabric around her calves and zōri with pale straps. She also sported a pair of green and pink butterfly hairpins that she wore adorned on either side of her head - one of which was later used by her adoptive younger sister, Kanao Tsuyuri, as a memento. She also wore the white, light green and pink butterfly-patterned haori that Shinobu Kocho now wears in the present.
Zenitsu Agatsuma (我あが妻つま 善ぜん逸いつ Agatsuma Zen'itsu?) is one of the main protagonists of Demon Slayer: Kimetsu no Yaiba and a traveling companion of Tanjiro Kamado. He is also a Demon Slayer in the Demon Slayer Corps.
Zenitsu is a young man with fair skin and downward-sloped, scared-looking eyes that fade from soft brown to gold. He has short, yellow hair of varying lengths, cutting off squarely at the ends where it fades to a darker orange color, that falls in front of his face in uneven bangs. Before he became a Demon Slayer, Zenitsu's hair was originally black, but it turned the color it is currently when he was struck by lightning during his training.
For some time following the battle at Natagumo Mountain, his limbs temporarily shrunk due to Demonic poison but were able to return to normal afterward thanks to the medicine given to him by Shinobu Kocho.
He wears a paler brown version of the standard Demon Slayer uniform, which consists of a dark brown gakuran jacket, a white belt around his waist and hakama pants that extend, as well as his signature white-triangle patterned, yellow and orange gradient haori. As well as this, Zenitsu also sports a pair of tabi socks, tied at the front in 3 white bows, with the same pattern as his haori, and white-laced footwear.
