Ghost Hunter 3000

I figured; why not put more mechas with anachronistic jobs online? Herein stands a Phantom-hunting robot, investigating a tomb. In this particular region, there have been reports of foolhardy explorers who ventured in here only to meet their doom. Only one person has ever come out alive, ranting mad about how the grounds are cursed.
Are these rumors true?
There only two ways to find out. One requires risking another life. The other involves spending thousands of yen on a mechanism to go in for them. They spent it quickly, expecting nothing more than booby traps or pitfalls.
As it turns out, the truth was far stranger than fiction...
