Following the massive operation that led to the confinement of recent recruit Kafka Hibino, otherwise known as Kaijuu No. 8, the Defense Force has been puzzled by how to deal with him. Kafka is the first kaijuu to side with humans, and after careful consideration, he is eventually transferred to the Defense Force's First Division in the hope of adding his power to the strongest division, capable of handling any threat. However, some people are still doubtful about Kafka, and he must prove his worth in the next mission. Kafka and the First Division are soon dispatched when a massive horde of ant-like kaijuu begins wreaking havoc. Thanks to the combined strength of Kafka's friend Kikoru Shinomiya and their captain, Gen Narumi, the mission seems to progress as it should. However, when Kafka fails to transform into his kaijuu form, the dreadful Kaijuu No. 9 joins the battle with only one goal—to eliminate him and steal his power. Although the situation is looking grim, Kafka must overcome his most difficult trial yet with the others if he wants to keep pursuing his dream: fighting side by side with his childhood friend and Third Division captain, Mina Ashiro.

In the novel The Lovely Princess, the secondary character Athanasia de Alger Obelia is the most pitiful of all. Her mother died in childbirth and her father, Emperor Claude, never gave his daughter even an inch of love. Forever yearning for even the slightest bit of parental love, she was ultimately framed for a crime and executed by the orders of her beloved father. When a woman from modern-day Korea falls asleep with some sleeping pills, she later awakens in the infant body of Athanasia. Knowing the unenviable fate that awaits her, she resolves to remain out of her tyrannical father's sight so that she may never incur his wrath. However, fate isn't so kind, and she meets him at only five years of age. With her original plan tossed out of the window, she now aims to endear herself so much to her father that he would never dream to hurt her. However, as many work toward their own ends, her plan is thrown into chaos—Athanasia's biological "sister" Jennette Margarita longs for a family, high-ranking nobility vie for power, and a shadow from Claude's past threatens to destroy everything he holds dear.
