Leviathan. Volume 1

A ghost ship slowly floating in open space hides a terrible secret.
Someone is hiding in the bowels of the Leviathan... Who is this - a monster or a confused person?

The huge starship Leviathan is drifting in space. What happened here? Marauders seeking to profit from the deserted ship find a schoolboy's diary. A boy named Kazuma set off on this ship with his classmates to Earth many years ago. The excursion never reached its destination.
Something happened... Explosions damaged the ship. They were attacked? Breakdown? It is unclear.
However, everyone who was on the Leviathan found themselves trapped in the void in a tin can, which will soon run out of air. Kazuma and his friend heard this when the teacher was talking to a service robot. The rescuers will not have time. Everyone will die. Except for whoever manages to reach the cryochamber at the heart of the ship. It can only accept one.

Only that person will have a chance to survive. But will you be able to call yourself human if you emerge victorious in a brutal battle for survival against everyone else?
