Now that we get an up close look at the protagonists, I can say without any doubts that the male protag's hair is crap. I wonder if their headbands hold any meaning though.
LOL, they actually got Uchida Yuma and Maaya (actual real life siblings) to voice the protags, who are twins. That's amazing. Uchida Maaya also does Sharena, and Yuma Seliph in Heroes.
If anyone's curious, this is what the "Story" part says:
On that day, the Kingdom of Aitoris became shrouded in darkness.
Without warning, the "Outrealm Gate" suddenly appeared in the royal castle.
Powerful monsters poured out of the gate, trampling over the royal soldiers.
—The castle quickly fell.
And the kingdom was slowly, but surely corrupted by darkness.
But, hope remained.
Two figures escaped from the flaming castle, "Shion" and "Lian", children of the deceased king.
With them, the strings of fate that tie them to the heroes of legend...
Wielding the "Shield of Flame" passed on from their mother,
The twins' stand against the great darkness begins here.
