In ancient times, aliens used human bodies to lock up their Troublemaker friends secretly. In 1380, a secret team of Fighters in masks tried to capture a strange woman, but aliens arrived in a car and their robots Thunder and guard used a glowing blade to free the alien. Sadly, the woman didn't survive, leaving behind a baby girl. Thunder brought the girl back to 2012, where guard now cares for her while dealing with new threats every 10 years. In 1391, wizard Murro uses magic to catch criminals for rewards.
