Zenitsu Agatsuma

Of typical height and lean yet toned, Zenitsu has fair skin and anxious, downturned eyes whose soft brown shade brightens into gold, framed by forked brows that warm into orange. His short hair sits at uneven lengths, ending in a squared cut that darkens toward orange and tumbles across his face in messy bangs reminiscent of a bowl cut. Black originally, it changed to its present hue after a lightning strike struck him in training. Following the clash at Mount Natagumo, poison from one of the spider demons shrank his limbs for a time, though medicine made by Shinobu Kocho restored them.

His outfit is a golden-brown take on the standard corps attire: a stand-collared button jacket with silver fastenings and a breast pocket, bearing the kanji for destroy on the back. A white collared undershirt sits beneath, with a white belt holding matching tattsuke-hakama wrapped at the calves by his bright yellow-to-orange leg guards, tied in front with three white bows in the same triangle motif as his haori. He completes the look with golden-brown tabi, white zori, and his trademark gradient haori patterned with repeating white triangles. As a grown man he imagined himself tall and mustachioed, but in truth he grew plump and barely managed any facial hair.

Timid, gloomy, and riddled with insecurity, Zenitsu often laments that his perilous work leaves him little time to live. His self-worth runs low even though he possesses genuine talent and might, and he frequently brands himself worthless. That mindset showed when, unable to accept that he had killed a demon, he convinced himself the slain figure was actually Shoichi, a powerless child. Perpetually frightened, he bolts at the first hint of peril and pines for an ordinary, quiet existence rather than a slayer's life, all while screaming and wailing at length.

Zenitsu practices Thunder Breathing, the discipline taught to him by Jigoro Kuwajima. Although panic regularly overwhelms his waking mind, he fights with extraordinary skill once he loses consciousness from fear, his reflexes and speed sharpening dramatically. His mastery centers on the first form, which he refined to an exceptional degree before later developing a technique entirely his own.
