Of Jumbled Storytelling Orders and Historical Aberrations

"Of Jumbled Storytelling Orders and Historical Aberrations" is a four-part mission carried out by Agents Kaguya Hazama and Momoka Shigisawa. It is episode 6 of the Four Demonly Kings spin-off, is part of the Beginning arc, and has the most parts out of any mission in the series. This mission marks the debut of Urato Tomiyama and Inasuke Akagashi, who along with Kaguya and Momoka would go on to form the Four Demonly Kings ensemble.

Synopsis
After Kaguya and Momoka have undertaken several missions, the latter worries that the former's "angry mode" would cause him to be lost in a fic. They then go on a Touken Ranbu mission, where Kaguya does indeed go missing despite Momoka's taking steps to prevent him from wandering off.

Momoka is approached by a stranger named K&#333;ga Ishitani, who insists they go forward with the mission even in Kaguya's absence. They observe the Mary Sue named Takara, who has a temporally impossible birth and background – is the granddaughter of Yūki Harutomo who died in 1614, but was born some time in the 1930s and experienced World War II – and an overly hostile and abusive personality – berating, physically attacking and confining Otegine for a prolonged period of time for not completely deferring to her. The fic's ignorance of history as well as glorification of the Sue's behavior, treating it as "tsundere" and romantic, angers both Momoka and Ishitani, but the latter more so – to the point of physical pain and bleeding.

Due to the fic's confusingly non-linear storytelling order, the two get to enter various flashback segments, where it comes to light that the Sue had a husband in her teens and abused a young boy for being unable to save his grandfather, a temporally impossible Oda Nobunaga, from murder. Both the Sue's teenaged husband and the abused boy are rescued, becoming Urato and Inasuke respectively. The four go to confront the Sue. Here, Ishitani disables his DORKS, revealing himself to be Kaguya in disguise, and charges the Sue. The agents and rescuees fail to defeat her, but she is killed by Otegine.

After treatment at Medical, Kaguya reveals to Momoka the reason he took the "Ishitani" disguise: the fic's badness caused him physical pain instead of "angry mode", and he needed a body that was both stronger to handle the fic for a longer period of time and unrecognizable to Momoka so she wouldn't worry. Urato and Inasuke undergo necessary procedures to become PPC agents.

Trivia

 * When referencing this mission later in the spin-off, Kaguya consistently refers to the Sue Takara as "Bakara".
