Chapter 4 Execution - Danganronpa 2: Goodbye Despair

"Chapter 4 Execution - Danganronpa 2: Goodbye Despair" is a high quality rip of the song "Oshioki Last Hike" - aka "Chapter 4 Execution" - from Danganronpa 2: Goodbye Despair.

Jokes
The advertised track is mashed up with "The Hampster Dance", the joke being that, in Chapter 4 of Danganronpa 2: Goodbye Despair, a character who was a hamster breeder was executed.

In addition, at 0:33, vocals from the advertised track are pitch-shifted into "Meet the Flintstones", and at the end, after the slow, poignant guitar section, we are surprised with another "BA--".
