Sephiria Arks in the manga
Number I, she wields 'Christ,' an exceptionally sharp sabre made of Orichalcum, known for its immense strength. Despite her gentle appearance and young age, her sword skills are remarkable, allowing her to strike with incredible speed and precision, often without making a sound. She can move so swiftly that she creates after-images to disorient opponents. Although young, she is charismatic and genuinely values life. It's said she can see into a person's soul, accurately guessing their feelings, which aids her in manipulating others, including Train Heartnet. While her ambition can lead to cruelty, she isn't inherently mean-spirited. Whether friend or foe, she despises unnecessary sacrifices, even willing to give her own life to defeat Creed Diskenth if needed, though Train intervened. In the final volume of Black Cat, she reveals her body has enhanced recovery due to being "born to live for Chronos," stating she "wouldn't die so easily." A master swordsman, she knows all thirty-six moves of her style, with 'Apocalypse' as the ultimate technique that utterly annihilates a target.

Her manipulative nature is toned down, presenting her as more direct and honest. She assists Train in battling Eden to rescue Eve after he wounds her pride. During these battles, she showcases her superior combat skills. By the end of the anime, she leaves to rebuild Chronos from the ground up.
