Nope, anyway, out of clues. Here is the answer.
Caple from Infinite Undiscovery.
1. Being lazy is the best
Refering to his starting title
2. I like girls, any type are fine!!
Again, refering to his starting title
3. There is nothing wrong in being a fake!
Refering to his mid game game title, and he did act as a double for his dad.
4. I am older than my dad
Sigmund reincarnated himself after Caple was born, so he is physically younger than his son.
5. I am among the trend of musicians being royalties
Caple is a muscian, and a prince.
6. Nibelung Valesti.... not
Refering to one of his tech, Green Valesti.
7. "Luke, I am your father!!" ....Oh, so that is why we look the same??
The lingering mystery on why Caple and Sigmund looks so much a like is because Sigmund is his dad.
8. "In the name of the moonn..." No, that does not weork for me either.
Caple is belongs to the people of new moon, thus has no power of the moon. Plus, he defeat Vera, the god of moon and rid of the moon's power completly.
9. I love fruit
Well, that is what he likes.
