They Were Eleven (Sub)

Tada is a young man on the fast track to the Cosmo Academy — a school which only accepts applicants every three years, and whose entrance rate is under 1%. Having passed all the prior exams, the final test is drawing near: survive for 53 days aboard a derelict spaceship with only 9 other would-be cadets to assist you. But much to the dismay of Tada and his peers, their ship has acquired an eleventh member! Can the crew band together to survive the test? Or will sabotage simply destroy them from within…
