Rewind

An unsuspecting 14 year old boy travels through time and ends up far in the past. He forms an unexpected alliance on his journey to get back to 2012, and runs into many giant, dangerous beasts. Although the boy, Rayre, knows that the giant beasts are completely abnormal, his last guess would be that someone is sending them after him. However, someone is, and not just anyone, but The President of Time himself.
