Months after the Universe Survival Saga, Goku lived his life normally again, following the same old routine. Slowly, he managed to learn the Ultra Instinct Technique, with Vegeta trying to follow suite. While starting a sparring match with Vegeta on a cliff, Goku disappeared, only to see that he was now in another world, another reality. Her reality . . . Aliza had known she was different from the rest. She was distant, away from the throng of students in high school. A few friends were already good enough, but she must not get too attached. She had a secret she wouldn't dare tell to anyone, and it'd be better to spend time alone-binge-watching some Dragon Ball episodes. While being in a get-together with her friends, she too disappeared, and was now in another reality. His reality . . . Their realities got exchanged. It was now up to them to find out why and how, as more secrets get revealed.
