J-rock artist Gackt has worked with Square Enix on a couple of projects like lending his songs to Dirge of Cerberus: Final Fantasy VII and voicing Genesis from Crisis Core: Final Fantasy VII.
Gackt will also play a key role in 3594e – Romance of the Three Kingdoms Hero’s Song, a cinematic RPG for iOS based on the Romance of the Three Kingdoms story. He voices Lu Bu and at the end of this trailer you can see a glimpse of Gackt dressed as the warlord.
Gackt’s biggest video game role still may be Lau from Bujingai where he was the model for the Wuxia swordfighter. One of the unlockables in Bujingai changes Lau’s costume into Gackt’s clothes so you can run through the game slicing up monsters dressed like Gackt.
