The Kagerou Project (カゲロウプロジェクト), also known as Kagerou Daze (カゲロウデイズ)[1] or Kagerou Days, sometimes referred to as Kagepro (カゲプロ), is a Japanese mixed-media project created by Jin (Shizen no Teki-P) (じん(自然の敵P)).
It initially began as a series of Vocaloid songs that became increasingly popular following the release of the third song, "Kagerou Daze". Eventually, a light novel and manga series, both under the name of Kagerou Daze, were released. In 2014, an anime by Shaft was also released under the name "Mekakucity Actors".[2][3]
