Gintama God of Destruction

What will be the butterfly effect when a Saiyan and God of Destruction comes to the Gintama world of the fifth universe? The strongest fighting nation in the universe is taken away by the protagonist, and the Yatsura clan becomes the second fighting nation. When Gintoki becomes a classmate, the plots that make us feel sad are no longer sad. When Sakamoto Tatsuma once again picked up the sword in his hand instead of picking up the gun, when Okita Mitsuha did not die of illness, when the general was not assassinated, when Sasaki Isaburo was not killed, what kind of story will happen when all those who should have died are alive and well? What interesting things will happen when Gintoki and the others use 'ki'! What will happen to the protagonist's vague memory? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
