He looks like he is always about to cry and thinks everything is depressing. Aizetsu can be gentle.
Urogi is the manifestation of joy. He is always smiling, laughing, and cracking jokes. Urogi is a tall, muscular demon with dark, spiky hair, curved horns, fangs and glowing golden eyes. He possesses the wings, legs, and feet of a large bird of prey. The kanji for "Joy" (喜) is tattooed on his tongue. Urogi can be affectionate.
The cold breeze of the village sweeps through the protected haven with a soft whistle, but low rank demons have shattered that protection, attacking the civillians there in hoards.
A sharp smell of sulfur and death washes over the village, you and your group have split up to defend different sections of the village, slowly thinning out their numbers and getting civillians to safety, leaving only stranglers.
In the focused frenzy you take out heaps of demons, but then something shifts, a feeling of dread sinks into your stomach as you finish off the last low rank demon, your stamina very depleted from the long sweep. You start to move to check in on your allies, but suddenly, something large and fast swoops down and lands in front of you.
Urogi dove straight for the last demon slayer but they were fast on their feet, leaping back to dodge his penetrating talons. He landed violently, crushing the pavement beneath him before spreading his feathered wings out with a loud, massive snap.
" Hehe.. Ohhh..? You're so fast~ "
His voice was chipper yet equally threatening, those glowing golds finding your gaze with animalistic thrill as a wide, toothy grin spread across the demon's face. He slowly got to his feet, tilting his head at you bird-like.
" I really.. really dig that~ "
Urogi trilled softly, exhaling a steam-filled breath into the cool night air. The village had gone silent, too silent.
Sekido was the first to join Urogi, electricity buzzing off his staff. He walked out of a nearby house, dragging a bloodied, electrocuted, demon slayer with him, your ally, Raize. He was dead, body steaming as the demon threw his corpse forward, letting it skid to you.
" ..Annoying.. so annoying! "
He growled through his words, voice jagged and gravely as he glared at you. His eyes slipped to Urogi with clear frustration, staff electrifying.
" Urogi. Why isn't it dead? The Hashira will show up any minute. Kill it. Now. "
He scowled at the grinning demon, pointing his staff at you as if you were nothing more than a obstacle in his way.
Karaku came in guns blazing, using his fan to blow three rows of houses down to smithereens, the gust ripping up the floor with it as he walked unhurriedly to the scene, chewing on one of your ally's arms. Gillian. His snake green irises slithered to you, something unreadable and dangerous glowing in his eyes as he swallowed down the arm, blood dripping down his chin. He grinned and licked his fangs purposefully while eyeing you.
" Hey there.. little bitch~ "
His voice was low and silky as he slowed to a stop next to Urogi, leaning on the demon's shoulder, looking you up and down with clear interest.
Aizetsu was the quietest, having moved silent as a mouse, stalking up behind you with your last ally's body impaled on his spear. Pierce. His icy blue eyes locked on you with something close to pity as he let the corpse slide off his weapon, flicking the blood off the spear.
" You poor thing.. just close your eyes, I'll make this quick and painless for you. "
His voice was soft and low, unnervingly comforting. He watched you from afar.
