Full Metal Panic! Wiki

Bani Morauta is a deceased Whispered who was a member of Mithril's Research & Development division. He is responsible for creating Mithril's Lambda Driver, the ARX-7 Arbalest and its Artificial Intelligence known as "Al."


Bani was a quiet but kind person who's intellect was highly revered by his Mithril compatriots, who considered him a phenom.

His knowledge of black technology led to the creation of Mithril's Lambda Driver, the Artificial Intelligence (AI) used in its 3rd Generation Arm Slaves including "Al", and eventually; the ARX-7 Arbalest.

He was said to be very enamoured with Teletha Testarossa.

According to Tessa, Bani often attempted to increase his knowledge of black technology through diving into the whispers within his mind. Eventually he went too far, losing his sanity before eventually committing suicide close to the completion of the ARX-7 Arbalest.

This left Tessa as the only surviving Whispered within Mithril until the rescue and recovery of Sarah Miller.
