Gongaga

Head due south until you reach something that looks like a burnt crater. Just after entering Gongaga, you'll have to battle Reno (II) and Rude (I). After defeating them, head to the right and then up to find a destroyed reactor. Tseng and Scarlet show up, so after they leave cheack where they were looking to find the Titan.

Go back to the trail and head left this time. Check the trail to the left to find the Deathblow, then head up to the village.

Go to the southernmost hut, then follow Aeris when she runs out. After talking to her, head to the northmost hut to find a White M-phone. The hut to the left of that one has an X-Potion. After you're done shopping, exit the village and head west in your buggy.
