It had now been 3 years since Ben took a chance at a normal life. However, history had a tendency to repeat and life had a tendency to be unfair. With the news of someone person putting in a good word for him at UA, Ben would once again don the Omnitrix and face the challenges ahead all the while having one question in mind: "Could he meet the legacy of that watch once again?"

Ben was given the master control to defend earth from invasion, but Azmuth soon saw it was a losing battle. The omnitrix was sent to a separate dimension to keep it from the wrong hands.

It had been quiet for two years after the fight with Diagon. Till a message from space arrived. Earth had been chosen as a member of the council. Earth would be kept safe, but in return Ben must give up the omnitrix. Ben made his decision but the omnitrix itself did not agree. Soon Ben finds out the true face of the council after escaping certain dead. Will he be on time?

It started when an alien device did what it did. Izuku Midoriya found a strange device on the beach one night after training when the device jumps onto his wrist.

Now at UA, Ben must prove himself a hero, or suffer the consequences.

No sense feeling sympathy for a dead girl." (Death game GGO, femKirito, yuri)
