The Sacred Kingdom has enjoyed a great many years without war thanks to a colossal wall constructed after a historic tragedy. They understand best how fragile peace can be. When the terrible demon Jaldabaoth takes to the field at the head of a united army of monstrous tribes, the Sacred Kingdom's leaders know their defenses are not enough. With the very existence of the country at stake, the pious have no choice but to seek help wherever they can get it, even if it means breaking taboo and parlaying with the undead king of the Nation of Darkness!

With the help of producer Masaya Kaburagi, Aquamarine "Aqua" Hoshino and Kana Arima have landed the roles of Touki and Tsurugi in Lala Lai Theatrical Company's stage adaptation of the popular manga series Tokyo Blade. Co-starring with them is Aqua's girlfriend, Akane Kurokawa, who plays Touki's fiancée, Princess Saya. Due to the fanbase preferring Tsurugi as Touki's love interest, Saya has made fewer and fewer appearances in the manga, making it difficult for Akane to fully immerse herself in the role. Her struggles are compounded by differences between the play's script and the original work—differences that also frustrate Tokyo Blade's author, Abiko Samejima. Aqua, however, is more concerned with his personal goals than he is with the play. He has only one objective in mind: to grow closer to director Toshirou Kindaichi and find out what he knows about Aqua's mother, Ai.

On the 20th floor of the Tower, the "Regulars" who have been permitted to enter have to undertake arduous and extremely expensive tests to rank up. Most abandon hope and choose to stay where they are—but not Ja Wangnan. Wangnan is determined to reach the top and become the king of the Tower. However, he is weak and has repeatedly failed the exam, with debt collectors tailing him. In desperation, he attempts the exam one more time, only to encounter a mysterious and powerful individual: Jyu Viole Grace, a member of the crime syndicate FUG. Cursing his rotten luck, Wangnan has no choice but to form alliances with strong people, including Viole—who still refuses to be part of any team. Amid a dire situation, Wangnan must find a way to change Viole's mind to finally advance past the 20th floor, or he will never get a chance to build his legacy.
