There are many planets in the universe. Yu Youyou has known about them for a long time, but only in recent years has the earth had some contact with other life forms in the universe. There are many people from other planets on the earth now, some are exchange students, some are here to help the earth speed up the "cosmicization" process. It is said that they are sent by the United Universe and the United Star Division, and some are simply here to visit. It seems that the high-level officials of the earth have agreed to the "tourism agreement" of other planets. For people on earth, no one expected that the planet they live on would change so much in just a few years, nor did they expect alien life to be so friendly.
However, one day Yu Youyou and his roommates accidentally overheard a huge conspiracy between an alien classmate and a mysterious person to develop the earth into a colony of their own planet. From then on, they had no chance of ordinary life.
So far, Yu Youyou has brought a frustrated descendant of Tiga, a borderline rich second-generation leopard girl who is half cat and half leopard, and a hidden evolved Saiyan.
He started a journey to save the world with an ordinary female college student who had her own personal space.
In this regard, Yu Youyou just wanted to say, "Thank you for the invitation. I really don't want to save the world. If I say too much, I will shed tears."
Mission: Save the world, friendship, responsibility
