This is a decently long story.

In the mystical world of Jopi, there lived 5 strange kukes(a type of gender). Each of them gave birth to 1 child. In the end, it turned out that 4 of those 5 children were ichukes(another gender). It is the tradition of Jopi, that only kukes can give birth to children, and that ichukes are completely useless. With their future generations in steady decline, the 5 strange kukes decided to name the one and only baby kuke as LUCKY, in hopes of keeping their species alive. When LUCKY grows up, it realizes the unfairness that ichukes have. One day, LUCKY sets off on a journey to help relieve the ichukes. The next day, one ichuke disappears, and LUCKY brings back a kuke. The 5 strange kukes are astonished, as their kind can only have one child. The next day, another ichuke disappears, and LUCKY brings back another kuke. By now, the 5 strange kukes are extremely grateful, but also curious about how LUCKY created kukes. The next day, another ichuke disappears, and LUCKY brings back another kuke. The 5 strange kukes realize that it has something to do with the disappearance of the ichukes and ask LUCKY how to create kukes. LUCKY responds by telling them the solution will reveal itself. Years pass, and the community is healthy and functioning. LUCKY still hasn't revealed the secret, but recently gets infected with a disease called BuBos. The 5 strange kukes are extremely old now, but are still curious about how LUCKY created so many kukes, so for the final time, they as LUCKY how it happened. LUCKY tells them that the solution will be revealed by itself if they let LUCKY go change more ichukes to kukes one more time. Because the 5 strange kukes really want to know, the let LUCKY go. LUCKY comes back, and the 5 strange kukes are eager to hear the answer. Then LUCKY dies of cancer
