Tsui Ling / Lapis

The girl Kazuma could not protect. She was sacrificed by a member of the Armagest (possibly Bernhardt Rhodes master) to summon a demon. Rhodes then used a spell to gather her remaining essence into a being called Lapis. Before her sacrifice, she and Kazuma worked in a restaurant, and were in love. According to Lapis in the last episode, her last thoughts were "Kazuma, I want to kill you." Whether this is true or lies meant to cause Kazuma pain is unknown(Tsui-Ling may have said this out of spite towards Kazuma for being unable to save her). As Lapis, she is trained in anti-mage fighting.
