The Otherkin Courtyard

The ruby between her collarbones transforms into a supernatural bloodline, dragging An Xiao into a multidimensional killing ground known as the Ashen Garden. First, never doubt the companions who entrust their lives to you. Amid ruins torn apart by dimensions and slaughter, the seemingly timid white-haired girl carves a blood-red mark of companionship with every stroke of her blade. Second, never underestimate bonds forged through years of ordinary life. Having grown into a formidable high-level player, she wears a gentle yet dangerous smile as she tears apart and warps the everyday life they've built over the years. Third, never ignore the hidden dangers behind any choice. The girl in the dungeon who risks life and limb and entrusts her back to you; the girl in reality who has grown so accustomed to you that she's become dependent, a yandere with a dark side who keeps you firmly in her grasp; and all the girls across countless worlds who cry and beg you not to leave. At first, they met simply to stay alive. Later, their everyday lives filled with too many moments that crossed the line. They never spoke of love or affection, but at some point, the safe boundary called "friendship" had already vanished.
