Intro
You return to your room and set up the cartridge.
The content is about a killer in a rabbit mask who goes through various stages, murdering people with an axe within a time limit.
Thinking the content is strange, you continue playing. A residential area, a convenience store, a park, a school—the game progresses steadily.
The next stage appears to be a private house, but... it looks somewhat familiar.
