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.
Wakuraba (病わくら葉ば Wakuraba?) was a member of the Twelve Kizuki, having held the position of Lower Rank Three (下か弦げんの参さん Kagen no San?).
Wakuraba was a man of average stature who had pale, grayish-white skin, with what appeared to be three large, cross-shaped scars cut into his cheeks and the center of his forehead and noticeably elf-like, pointed ears. His eyes were wide and sharp with orange irises, the kanji for "Three" etched into his left, as well as short, black hair and a widow's peak.
Wakuraba wore a dotted, bamboo-colored yukata with a pinstripe pattern, a piece of dark cloth around his waist, and a lighter one around his neck, as well as two golden hoop earrings on each ear and a pair of wooden sandals with black straps.
