When you pre-order Final Fantasy XIII-2 in Japan, you’ll receive a download code for a new weapon for Serah. Today, Square Enix provided a first look at the sword/bow combination, called “Seraphic Wing.”
The weapon will eat up energy from the monsters it attacks.
It is also obtainable in-game, without a download code, though when found it will not be in the same color.
Thanks, Famitsu.
