Kyosuke Sakurai – you – awaken
in the city of Shibuya, Tokyo, oddly quiet and devoid of its bustle.
Nobody is around. The only exception is the
group of eight childhood friends,
which you used to be a part of.
As the group gathers in the city's
famous scramble crossing, a blood-red message
flashes on a nearby electronic billboard:
「I am dead. Who killed me?」
If this world is similar to the Chronos Worlds
that had emerged in the past, there is only one way out –
to find the one causing this strange phenomenon,
and kill them.
