Soul Link

In AD 2045, a group of military cadets attending the preparatory course of the Central Military Academy transfer to the space station Aries for zero-g training. This class of cadets includes Ryota Aizawa, Sayaka Nagase and Kazuhiko Nitta. Their training is interrupted when a terrorist group called "Hallarax" takes over the station. While the military successfully evacuates the civilians on board the station, Ryota and his group are trapped. Worse still, the boarding assault has left most of the military personnel dead, effectively leaving the cadets on their own.

An unexpected twist occurs when a mysterious virus is released within the station, which turns those infected into mindless creatures. This forces everyone, friend and foe alike, to work together to find a way off of the station alive.
