Bani Morauta is a deceased Whispered who was a member of Mithril's Research & Development division. He is responsible for creating the ARX-6 Halberd and ARX-7 Arbalest and its AI "AL." He had a crush on Tessa before he died. According to Tessa, Bani attempted to increase his Whispered knowledge through resonance. He lost his mind soon after and committed suicide, leaving Tessa as the only surviving Whispered in Mithril. This was right before the completion of the ARX-7 Arbalest.
