Michibikareshi Mono-tachi no Rakuen ~BEDLAM~

A large building stands alone in the middle of nowhere, surrounded by empty land.
It’s an old medical facility, built far from any town or village.
After lying dormant for years, the place has quietly come back to life, operating in secret.
But only a select few know it’s still in use.
After all, this isn’t the kind of facility that can be made public…
