Go to the corner of the mountain base and the hermit trainer will appear. He will give you a special fruit that will allow you to use the Rokushiki Soru. This move is considered to be one of the most powerful moves in the Fruit Battlegrounds and will help take you to the next level of the game.
To use the Rokushiki Soru, you must first select the fruit that you obtained from the hermit trainer. Once selected, you can use the left joystick on your controller to move in a circular motion. As you do this, your character will move around rapidly, allowing you to move quickly and make quick decisions.
In addition to the Rokushiki Soru, you can also select other fruits from the hermit trainer that will help you in battle. These can range from items that will help you heal up after battle to items that will increase your attack power.
Once you have obtained the fruit, you can now use it in battle. To use the Rokushiki Soru, press the left joystick in the direction you want to move and a powerful blast of energy will be released that will blow up obstacles.
