Kono Yo no Owari e no Tabi(2002)

Every morning a man wakes up, gets dressed, and heads to work, returning home in the evening to go to sleep. Feeling suffocated by the mundanity and repetitiveness of life, the man takes a detour on his way to work one day. But after being swept up in a tide of piracy, cannibalism, and bizarre religious sects the man starts to wonder: was his boring old life so bad after all?
