Ace: Although my Heart may be weak, but it's not alone. Its grown to each new experience, and it's found the home with all the friends I've made. I've become a part of their heart just as they've become a part of mine. And if they think of me now and then... if they don't forget me... then our hearts will be one. I don't need a Sword. My friends are my power!
