Dante activated his superpower once more and chose to return to the real world. His body separated from the one in the quantum realm while his mind remained intact in the sense that he remained logged in despite his body being sent back to reality.
He also lost that feeling of tangibility and he could definitely notice the difference between having his mind in a virtual space compared to using his body. This was actually somewhat good because unlike normal residents of this universe who felt like the virtual world was 100% real, Dante would not fall into that trap.
In other words, he never had to fear becoming unable to tell real from virtual. How nice.
Dante looked around and knew he could not just leave his body there. He decided to sprint back the way they came and spent almost 10 minutes running at a speed of around 200 kilometers per hour which was close to his top speed before he saw light.
