There are infinite alternate timelines in which the Universe exists. In certain timelines, however, incedents happen in which kittens are subject to animal cruelty. In each of those instances, the ghost incarnation of Happycat avenges those kittnes in one way or another. Not Even Doom Music can save the souls of those who harmed those kittens.
In NEDM Avenger, you play as the feline incarnation Happycat in different timelines avenging and saving kittens.
This game is inspired by a true story.
