Jungle Juice, Vol. 2 (manga)

Suchan’s determined to become the top student at NEST—and that means getting an A on his first group assignment! Their task? Return to the real world and track down a single can of Jungle Juice. Save for being extraordinarily difficult to find, the job should be relatively uneventful...or so it would seem. Shortly after Suchan and his team manage to get a lead, Professor Ji receives a frantic visit from his T.A.—claiming that someone from Suchan’s group has died...!
