Kenja Lain

As one of the sages of another world, Lain holds the highest rank among true ancestor vampires, possessing an immortal bloodline of the Origin Blood lineage. Weary of her endless immortal existence and driven by a deep desire to save her younger sister, she became intensely fascinated by Yogiri Takatou's instant-death ability. Calm in demeanor and meticulous in planning, she went so far as to dispatch her own clone to probe his true capabilities. Though her main body was ultimately slain, she had already prepared a reincarnation contingency, allowing a new life to emerge from her defeat.
