To escape, Makoto has to help the people around him face their own personal problems. Though invisible to others and able to walk through walls, Makoto discovers that he is still able to manipulate objects if his will is strong enough.

Makoto is now forced to embark on a mission to save the same people he tried to leave behind and face the unexpected ways his death affected each of them.
