Reach for the stars- Reach up for Memoria or go up for it,

And your dreams will come true- It's a place of dreams so you'll see your dreams and past,

I could be a coward- The boss inside(Nova Dragon) could be weak for sending all the other dragons to do his work,

but only to you- To the dragons it's really strong,:riiight:

I may not be strong- It's not strong,

but my talent I gain- It's the Nova Dragon and it does some type of wave blast thing ,I think, and it's sorta like a nova,:riiight:

I say who I am- It says who it is with it's attack discribed in the previous line,

but thats not what you need- It won't help you what so ever,

The answer is there- The answer to defeating it is there somewhere,

but on time do not heed- Don't waste time trying to figure out the weakness or it'll kill your party(Thats why you get strategy guide to find out its weakness)
You probobly already know but my guess is the Nova Dragon and it's probobly really wrong and far from the answer.
