Go to Goug Machine City during Chapter 4. Mustadio's father will
demonstrate a weird machine.
After that, go to Goland Coal City and listen to rumors at the bar. One

having a breakdown. Your goal is to save Cloud. Afterwards, Cloud will

must be equipped with the Materia Blade. If you point to Cloud's name in
the status screen, he says "It's hidden on the top of the volcano!" That
