How do three-dimensional people live in the second dimension? Especially in the second dimension of Gintama, can that nose-picking man be trusted? And why did Lu Xing become as complaining as Shinpachi after entering the world of Gintama? Others can level up by traveling through time and fighting monsters, but how come they almost die every time they come to him?
Intention: Why is it so difficult to return to the third dimension? Why is the world of Gintama so chaotic?
