Sin

A warrior from the Gards-orm who works with Abyss. Though she has the appearance of a human woman, she infiltrates the Oceanus alone, intrigued by why the "Lightless" Celebrants fight. Demonstrating extraordinary abilities such as hacking into the Oceanus’ security system, she also overwhelms Lucia in close combat. She grows fond of Ryoko, who answers her questions, and repairs her damaged phantom body; however, she shows no mercy during battles. After the battle at the Maihama server, her phantom body is found but severely damaged. She vanishes while being watched over by her new friend, Ryoko, as her physical body crumbles.
