カゲロウデイズ (Kagerou Daze) (2024)

Background[]

“An old story speaking of summer.
「It's because I hate summer」”
—Author's comment

Jin's third work and one of the tracks for the Kagerou Project. It is one of his most notable songs; the original Nico Nico upload has over six million views.

"A song that will overwhelm your eyes." The story behind the song revolves around a boy, Hibiya, and a girl, Hiyori. On August 15, Hibiya witnesses Hiyori running out into the street to retrieve a black cat and getting hit by a truck. The heat apparently mocks him in his daze, and he blacks out. He wakes up and it is August 14. He tells Hiyori about his strange dream that took place in the park they were walking in. Just as she steps in front of him, a pole falls from the sky and pierces through her. The heat once again laughs at him, and, before he blacks out, he notices Hiyori seems to be smiling as she dies. This process repeats for decades, the same two days happening again and again. Finally, Hibiya decides to take action and pushes Hiyori out of the way of the truck and is killed himself. In the end, it shows Hiyori was also caught in the loop. It turns out that she had been trying to save Hibiya from death, so the cycle still continues on.

The remastered version uploaded in 2012 can be found in the album Mekakucity Days.
