Will It Be the Computer or Lupin?

The one and only supposedly perfect safe in the world is housed inside a VTOL aircraft. And it is guarded by a supposedly almighty defense computer, programmed with all of Lupin's data, making it Professor Hunter's masterpiece. On a sudden impulse, Old Man Zenigata steals one of the throwing coins of his great Edo-period ancestor, Zenigata Heiji, and ends up carrying out a strange team-up operation with Lupin to put it back again. Is it possible to escape from an infinite maze?
