Martian Successor Nadesico
The Meadows We Once Ran Across
S1 E21:
The Nadesico's new mission is to defend the moon using its new phase-transition cannon, but when something goes wrong with the Y Unit, the weapon becomes inoperable. With only an hour to repair it, the ship's pilots must discover what happened, a task made more difficult because their minds are currently linked in an illusory "memory mahjongg" game.
