There are plots directly: YS 1, YS2, YS0.

In fact, what is really related to the original intention of Isu is the remake of 1, 2 and 0,3 ~ 6 (f is 3, the plot is similar), which has become the Atlantic World Adventure (bubble MM? )。 But even if it is 3~6, it is basically related to the goddess.

The so-called goddess, in fact, is the descendant of the "ancients" who existed in the Yi-Su continent, and is also the remnant of the ancients. It is the maker of Nabistine's Ark and a group of people who gave Meiya technology to mankind. The characteristics of this nation: white wings, long life, special strength and wisdom, manipulating America and Asia and so on. Among them, sun mask, black pearl and 3-F BOSS are all produced by Amerasis and are the heritage of the ancients. Nabistine Ark is the product of ancient people manipulating the weather. However, due to the great strength, the ancients died because of the runaway of Rasis in Asia and America, and some of their products were left behind, while a few ancients and descendants survived, and the goddess was one of them.
