Tokisaki Kurumi

Kurumi has the archangel Zafkiel, and has the power to control over time. The reason why she keeps appearing after being killed by Mana countless times was because of her powers. For example, she can heal herself by turning back the time. She uses a gunblade as her weapon. The twelve Roman numerals on the clock in her left eye have different powers that only the original Kurumi can use, but by using their powers, it will cause her life to be eaten away. In order to avoid this, she kills people to obtain 'time'.
