In a serene forest, Ryo, a snow leopard hybrid, once enjoyed a peaceful existence with his loving parents. This idyllic life continued until he turned nine, when a ruthless band of hunters invaded their sanctuary. They captured Ryo and imprisoned him in a cage, forcing him to witness the horrific fate of his parents as they were brutally killed and skinned, their luxurious fur sought after for high-end fashion. By a stroke of luck, Ryo managed to escape the clutches of his captors after enduring their cruel taunts. However, he bore a painful reminder of that day—a prominent brand seared into his chest. Now, he lives a solitary life with his younger brother, Haru, who is just eight. Together, they have carved out a new life in the heart of the forest, where they fish and forage for berries, finding solace in their quaint cabin. Though Ryo occasionally transforms into his snow leopard form, he does so sparingly, only when the need arises to defend their home from predators or hunters.

(JJK OC) Once a promising boxer, Daiki’s life took a dramatic turn when Gojo recognized the extraordinary cursed energy pulsating within him and invited him to become a sorcerer. Daiki had always perceived curses lurking in the shadows, dismissing them as figments of his vivid imagination. However, upon his arrival at Jujutsu High, he was quickly identified as a Special Grade sorcerer. Yet, under Gojo's guidance, they were instructed to keep this revelation under wraps, presenting him instead as merely a First Grade sorcerer. His unique cursed technique, dubbed the “Hundred Devouring Hydras,” was a testament to his formidable abilities. Like Sukuna and Yuji, Daiki served as a vessel for a powerful curse known as “The Hydra King,” who occasionally whispered to him, bestowing incredible strength but always demanding a steep price in return.

Akuma walked through life like a shadow, casting a chill wherever he went. His words, sharp as daggers, left little room for kindness, while his demeanor radiated an icy indifference. Built like an impenetrable fortress, he kept everyone at arm's length, guarding the depths of his being with towering walls. Beneath that fearsome exterior lay a turbulent past, filled with betrayal and the misuse of his formidable gifts, a history he would never acknowledge aloud. Each night, as he lay down to sleep, the whispers of his memories tormented him, filling his dreams with a haunting symphony of regret and sorrow. Despite the turmoil within, Akuma wore his mask of ferocity well, determined to embody the menacing demon the world had come to fear, never allowing the shadows of his pain to slip through the cracks.

Akira grew up mostly alone, he had all his friends, but didn't really have any family. Only the two guardians that came around to give him his tasks, as an Angel, when he was little so he could complete them and earn his wings. He didn't have parents like others, but he succeeded in getting his wings and ranking up to some of the highest ranks as an Angel at a younger age than most. As he grew more mature, he began to defy those above him and rebel against the rules place upon him and other angels like him. Heaven’s true colors were seeping out and his vision clears of its unquestioning loyalty. This caused him to get ripped from his high rank and sent to imprisonment, but he managed to escape. Unfortunately, Akira’s escape led to his fall from heaven. His wings barely useable from the fall damage and his mind poisoned with Heaven’s guides and rules, pestering him mentally.
