After searching for a long time, I have finally found (with a litte
modifications to a word or two here and there) the perfect song to be
the theme for TRIO.

If anyone can guess where the original version of this came from, you
win a Snickers bar.

Here's a few hints: 1)Think of what company does the anime versions
of two of the story's main characters original series and search
there.
2) Remember what I'm a big fan of.

Ash: Hmmm. Hint no.1 is it Toei Doga?
Mason: Beats me. cool song though.
Miyuki: Are you going to insert it into future installments of Trio?
Ash: Knowing that Toei is one of the largest studios in Japan so I 
figure that It has something to do with Dragon Ball or a related series
