Also known as Senga (センガー/閃牙 lit. "Flash Fang"). It is one of the eight Sacred Treasures that comprise the OutRage and Sol's creation. It is a Magic Amplification device that channels and intensifies light magic. It was previously located at Harden Fort and under the custody of the U.N. until Sol came to retrieve it in order to reassemble the OutRage.

After seeing the Gun Smith Dog recommended by Dr. Paradigm to help in the construction of the Junkyard Dog MKII casing, Sol was successfully able to merge the Fireseal with the Senga.
