O-Parts (2012)

In the year 2141, Japan successfully builds a basic time machine that can send data to the past. However, an evil organization further develops the technology, making it possible to send objects back in time as well. The organization begins a plan to send 5 terrorists back to the year 2012 in order to assassinate the ancestor of an important person from their time. The future government, alerted to this fact, uses its time machine to notify the government of 2012 about the plot, telling them to recruit 5 people in order to seek out the terrorists.
