Destiny Road[]
Kiana and Shigure Kira in Siberia
More than a decade later, Cecilia's daughter Kiana Kaslana grew up and became a B-rank Valkyrie of Schicksal. To teach Kiana, Kira took Kiana to West Siberia to participate in her investigation mission. But Kiana accidentally caused an avalanche during training, which awakened Kukulkan which was sleeping in the snow-capped mountain. That was the follower of the Second Herrscher, and was also the strong enemy who had successfully blocked Kira's way to help Cecilia. Recalling that battle, and seeing it hurt Kiana right now, Kira exploded with unprecedented anger. Fortunately, under the influence of Kiana, she calmed down, and with the help of Kiana, she successfully killed the old enemy that had been many years ago. Kira believes that Kiana has this ability to become stronger. The person protected back then was herself, and it was her turn to protect Cecilia's daughter.
The Third Great Houkai[]
After Kiana was captured by Anti-Entropy in Changkong City, she followed Hyperion to attack Anti-Entropy and forced them back to the Moonlight Throne. After that, she went to New Zealand and worked with Ninti Apokalypse to solve the 4th Herrscher incident.
St. Freya Academy was later destroyed, Cecilia's whereabouts are unknown, and Schicksal pursues Anti-Entropy. To fulfill Cecilia's request, Kira betrayed Schicksal. When Kiana fell into despair and was about to be killed by Maria Schariac, Shigure Kira appeared and stopped Maria.
After obtaining the consent of Cocolia, to fulfill the agreement with Cecilia, Kira once again brought Kiana to Aurora City. She knew that the sealed Aurora City had Cecilia's secrets about the saint that she wanted to convey to Kiana. As far as Kira looked, telling Kiana the secret is to let Kiana get the right to choose and get rid of the arranged destiny. But things didn't seem to be that simple. Aurora City appeared in front of them, and after confirming Kiana's determination, she handed over the books left by Cecilia, and to verify the authenticity, she mentioned the events of her own time and the oriental immortal named Fu Hua.
Shigure Kira death scene
The Schicksal gained the approximate location of Anti-Entropy through "Theresa" A-374, and found the hidden base of Anti-Entropy after careful investigation, to wipe out them. And Anti-Entropy has also prepared a way to deal with it, ready to use the natural terrain advantages to fight for some chances of victory for itself. Cocolia not only sent the War God to ambush but also asked Shigure Kira to take Kiana and Mei to contain her. On the frontal battlefield, Kira alone took on the task of involving Maria. After a fierce battle, Shigure Kira defeated Maria. They had been close to sisters because of the same longing and finally had a chance to talk. Although a brief conversation at such a tense time couldn't make them fully understand each other, they didn't have the opportunity. Angelia Schariac, who had successfully undergone the experiment and transformed into an artificial Herrscher, appeared on the battlefield and dealing the final blow to Shigure Kira. As she died, Kira knelt in the snow to send her last blessings to Kiana.
