Japanese need help with translating a phrase

well I have this anime-ish story i'm working on, i've worked on it for over 9 years. now i'm making the story titles in romanji.

what does "I will tell you! The story from long ago" translate to in romanji?

some japanese language anime words, phrases I know:

Sekai Daikai = World Tournament
Makai = Demon World
Mamono = Demon/Devil
Yume = Dream
Ai = Love
Onii-chan = Big Brother
Mirai = Future
Yuusha = Hero
Senshi = Soldier/Warrior
no = of
Konjiki = Golden
Yamaneko = Mountain Cat
Seiryuu = Blue Dragon
Genbu = Black Turtle
Byakko = White Tiger
Suzaku = Red Phoenix
Bakuten = Bomb
Obaasan = Old Woman

 

I believe "Mukashi no hanashi, suru ne!" is proper for it.

mukashi no hanashi = the story from long ago
suru = will do (meaning even "will tell")
ne = an particle for coordination of the saying functions

In Japanese, I can't express the nuance of the last "!" well.
