I'd live in the Dragon Ball universe because it reminds me of the wild west with lots of exploration, dinosaur ridin', wishing for underwear havin, fightin' bad guy hijinks. Until it moves to Z and then everyone keeps dying every like 10 years when a bad guy invades and blows the earth up.
This is a good answer but also for another reason: You can literally do anything with enough hard work. What a wonderful fantasy.
Like if I lived in the Dragon Ball universe I would simply work out until I can punch gods to death and then nobody could kill me.
