Kiana stepped forward in the subsequent Honkai books, absorbing the power of all the Herrscher cores and 99% of the Honkai energy on the earth, transforming herself into an existence comparable to the Final Herrscher, combining herself and The Herrscher of the End was sealed on the moon together. Assuming that the post-Honkai books are what happened after the Honkai Impact, the conclusion that can be drawn is that Kiana Ikkiko is most likely gone.
Introduction to Kiana in the post-Honkai books
Kiana Kaslana, the heroine in the mobile game Honkai Impact 3rd and its derivative works, the Herrscher of Destiny Physical test subject No. K423, a high school student at Senba Academy, a student at St. Freya Academy, and a Destiny B-level Valkyrie.
Under Otto's planning, the Herrscher personality awakened and took over his body. After being injected with the God-killing Spear by Himeko, Kiana's consciousness returned. Later, he appeared in Tianqiong City and began to try to control the Herrscher energy in his body. He has now learned to control part of the Herrscher's power.
The daughter of Cecilia Shaniat and Siegfried Kaslana, who has the blood of Kaslana and Shaniat, the two major families of Destiny, was named Kia by Theresa Na means the moonlight goddess.
When Kiana was 2 years old, her mother Cecilia and the Second Herrscher died together. Siegfried, who learned that Cecilia died in a nuclear bomb ordered by Otto, was disappointed with his destiny and escaped from it with the help of Theresa in 2009. However, Siegfried, whose plan had already been discovered by Destiny Bishop Otto, only reluctantly took away Kiana's clone K423, while Kiana was recovered by Destiny.
