Fragments of an ancient legendary artifact, called a Relic, fashioned into a pendant. Upon singing its activation chant, it will transform into armor and create a weapon called an "Armed Gear". Symphogears are powered by Phonic Gain, which is generated by singing the song in your heart. You can also sing a "Superb Song" which, when sung, will temporarily use the full power of the Symphogear. Using a Superb Song can cause backlash to your body if there is disharmony between you and the Relic. You will be a natural Adapter, capable of using the Relic with a high Sync Rate.
