Tsui Ling

History
Tsui-Ling ( (翠鈴, Tsuoi Rin ) was Kazuma's former lover during his exile in China. Kazuma loved her dearly. At one point Tsui Ling and Kazuma were captured by Stars and Sagacity.

She was sacrificed by the head of the Armagest, Bernhardt Rhodes, to summon a demon. Rhodes used a spell to gather her remaining essence into a being he called Lapis. Before her sacrifice, she and Kazuma worked in a restaurant and were in love. In the last episode Lapis states that her last thoughts were that she wished Kazuma was dead. Whether this is the truth or a lie meant to cause Kazuma pain is unknown (Kazuma notes that she may have said this out of spite towards his inability to save her). As Lapis, she is trained in anti-mage fighting.

Legacy
Tsui Ling is occasionally seen throughout the series when Kazuma is in some distress. Her death and Kazuma's inability to keep his promise to protect her became his driving force to protect everyone with his wind powers. Her image would also be used against Kazuma to haunt him as Bernhardt Rhodes would use her image to torment Kazuma through Lapis, a near identical replica of Tsui Ling born from her final thoughts.
