In the year Age 852, a mysterious scientist named Fu began tampering history through space-time that resulted in the creation of multiple time rifts all over Time Patrol HQ. The Time Patrol soon investigated this new threat and managed to resolve the matter, depsite keeping their guard up against Fu as the Time Patrollers are reluctant to fully trust him. However, the enigmatic scientist isn't responisble for the creation of the time rifts even though he was behind tampering with history by creating alternate timelines that has no effect on the true main timeline.
This eventually leads to discovering the true mastermind, Dabura! Hailing from an alterate future, he seeks revenge against the Time Patrol for killing his sister Towa and will finish what she and Dabura have started: stealing energy from changes in history to revive the Demon Realm of Universe 7. These revelations even reveal that Fu is the son of Towa and her creation Mira, and the nephew of the Demon King Dabura himself.
Suddenly, Fu openely defied his uncle and easily defeats him. He then reveals his true motives to the Time Patrol. He explains that the reason he gathers energy in the changes of history he makes is because he loves to experiment different scenarios in multiple timelines to better the world with good intentions as he has no interest in seeking revenge or reviving the Demon Realm. Since that's considered illegal to the laws of space-time, the Time Patrol attempted to capture him but manages to escape, hoping to see them again and continue his experiments as well. Seeing that Fu is no longer a threat to them, the Time Patrol suggested to keep a close eye on him should he causes trouble, despite his neutral intentions between good and evil. Looks like everything has turned out for everyone.
Or so they thought...
