An Iori-class star fortress formerly found above the colony of Taiie in the Bard Cluster. Taiie no Iori was to be the base of operations for the Fifth Expeditionary Fleet. However, before it could be finished, the KAMI unit was sabotaged and turned on the occupants of the fortress. Many promising young commissioned and enlisted officers were killed as a result of the KAMI's rage. Though the unit's consciousness, manifested through a male sprite named “Ichiro,” eventually transferred to the original Akuro, a Chiharu-class Flagship, it left Taiie no Iori in ruins. The site was turned into a memorial for a short time, and a second Iori-class was removed from reserve and set up.
The sabotage was thought to be done by a disgruntled technician, but in reality, it was Star Army Intelligence attempting to kill Motoyoshi, who had resisted their orders for far too long. The plan was lost, however, when Motoyoshi left the Iori temporarily and the KAMI had no target to destroy.
The events of the Iori's birth and demise are chronicled in the 5th XF Archive. It is a three-mission series with a prologue and an epilogue.
