You can do this with the Module :: nesting method :

nesting -> array

Returns a list of modules nested within the caller.

module M
  class C
    Module.nesting[1] # => M
  end
end

If you want to get this value from instance methods, you can assign it to a class variable:

module Hello    
  class Hi
    @@parent = Module.nesting[1]

    def initialize()
      puts @@parent # => Hello
    end
  end
end
