Kagerou Daze

The Kagerou Daze (カゲロウデイズ Kagerō Deizu, lit. Heat Haze Daze), also known as simply the Kagerou (カゲロウ Kagerō, Lit. Heat Haze) or the Daze (デイズ Deizu) is a never ending world created by Azami.

Description

 * The Kagerou Daze is a never ending world created by Azami, who was convinced by the Snake of Clearing Eyes to make it. Azami originally intended to live in this world with her family due to the fact that humans age much faster than her, she would've outlive her husband Tsukihiko, who was human, and their daughter, Shion. Tsukihiko wanted them to have a traditional wedding, so he went back to his village to get a wedding dress, but he was detained and beaten by the villagers about Azami. While waiting for Tsukihiko to come back, Azami and Shion are attacked by villagers. Azami retaliated by using her abilities and killed all but one, and used Stealing Eyes on him and saw what happened to Tsukihiko, and she decided to enter into the Kagerou Dazealone to not cause any more suffering to him and Shion. This world was revealed to be terrible, and Azami had been tricked by the Snake of Clearing Eyes.


 * As time passed, her daughter, Shion, as well as her granddaughter, Marry, were murdered by humans and Azami ordered the Kagerou Daze to swallow them up, resulting in the Kagerou swallowing anyone dying on August 15th. Wishing for at least her granddaughter to live, Azami gave her the Queen of the Snakes, also know as the "Snake of Combining Eyes", which would serve as a surrogate life for Marry, while Shion remained.


 * Azami lost her ability to unite the snakes because of this, so she was unable to undo the order she gave to the Kagerou Daze: "Bring in the people who died on August 15 (the day of Shion and Marry's deaths)". To enter the Kagerou Daze, a living creature must die on August 15th. It's possible for one of the snakes to possesses someone swallowed into the Kagerou, acting as a surrogate life and giving them an eye ability, which also makes it possible for them to leave the Kagerou, while others don't and remain inside the Kagerou Daze.


 * Azami is able to trap the Snake of Clearing Eyes in the Kagerou Daze by regaining control of 5 of her 10 snakes in the novel, but is unable to defeat him, resulting in Marry rewinding time again.

Trivia

 * The locations where each character is shown for the first time in the anime are the locations of their individual deaths, excluding Marry.
