There are four gates in Galaxy Bridge. The one you came through obviously goes back to Asdivine. The one on the west goes to Lamel, and the one on the east goes to Susha. (Both of these gates are inactive when you enter Galaxy Bridge.)
The south gate - and the one you want - leads to Estrella. But, someone has placed a barrier along the path, blocking your way, and since Izayoi doesn't know who put it there, he's not willing to dispel it.
As you're discussing your options, a Blond Magic-User appears and fires a magic shot at Ratona! The magic user is joined by a Mysterious Woman, and together they force Izayoi and Ratona through the gate to Lamel, a world that is entirely submerged in water.
