[*********** -ren series 9-]

a man is under control of a timer machine.
the machine repeats supplying and shutting the air alternately each 40 seconds.
ren turns on the machine.

then, he is left.
it is the start of his solitary fighting with fear.
the interval (40 sec) is too long for him.
he gets panic little by little.

he is made to challenge in this situation twice.
the second time is longer than the first one.
