The first mission available is The Ranch Owner, You must go to the city of Mile and kill the Big Sand Worm. Seems pretty easy but not as simple as you think. So get ready for a good fight!
The Thinkerbell's Dog mission becomes available when you get the Land Rover. You must rescue Rockie, the lost dog of a little girl. First you must buy a shortcake at the Aiedo's bakery, then go to Monsen and find the dog. If he flees, it's because you don't have shortcake.
The Missing Student is one of the easiest mission. It becomes available when you defeat Zio. You only have to buy a perolymate at Termi's Gift shop. Then go to Zio's Church and talk to the girl. When she's in the bed, talk to the old man and then talk to her again. Now get your reward!
This mission is not too hard, an not too easy neither. A little curious boy felt in the Fissure of Fear an you have to rescue him. Go to Monsen, talk to his mother, then go in the Fissure. You must hurry before it is too late...
If you have time to lose, take the Stain in Life mission, you win nothing, you lose nothing (except time). Here is how to do it : go talk to the parents of these two girls, then you only have to go to the Aiedo jail and pay the jailkeeper!
Here is another boring mission, the Dying Boy. He lives in Torinco and he claims to be sick. Go in Termi, buy the Alis-Sword (a small plastic toy) and bring it to him. He'll magically be recovered!
