Dragon Ball - Gohan x Trunks After (Doujinshi)

The story this time occurs because of Future Trunks' frequentent ventures through time, as a result a new timeline no one knows about was born.

No time machine was made in this world, so Future Trunks had no means to travel to the world of the past.

As a result, Gohan and Trunks are the last two warriors standing in their quest to protect the Earth. Are they strong enough, though?
