XV Episode 4
A decisive combat function incorporated into the Symphogears when they were rebuilt by the Lapis's crimson brilliance.
It comes from the structural similarities between the Symphogears and the Faust Robes that results in the mixing and fusion of their formation energies.
The name "Amalgam" was something created by Elfnein, meaning a sort of alchemical alloy or "fusion specimen."
Upon activation, it instantly releases the energy that composes the Symphogear and reforms it into a golden "cocoon," a first stage that gives the user a far more powerful barrier field (and that consumes far more energy) than normal.
Next, the energy is reformed into a high-output armed gear, reorganizing into into an "imago" that serves as a second stage.
Put simply, it causes an extreme disbalance between defensive and offensive parameters.
In the "cocoon" stage, defensive ability is greatly raised while attack power is greatly hampered.
In the "imago" stage, attack power is greatly raised while defensive power is greatly hampered.
As a result, the number of situations where this ability is useful is limited.
Despite its apparent lack of flexibility, for the Adapators who have been practicing and training with many of the Symphogear's special functions (starting with G3FA), it is seen not as a new restraint but is hoped to become a potential alternative to the power offered by the destroyed Ignite Module.
For a time after the initial rebuild, Amalgam's functionality had laid dormant, but has now abruptly awakened.
This is thought to be due to some sort of lock being released when the Symphogears suffered the attack known as Daedalus End.
The first to master this technique, Tachibana Hibiki, claimed it was due to her former rival-turned-friend guiding her through a state of murky consciousness, though there is no firm evidence to support her claims and they must therefore be dismissed as nothing more than a "cool story."
It's not very widely known, but in the medical field there's debate over the existence of a phenomenon known as "memory transfer," where an organ transplant patient receives a portion of the donor's memories along with the organ.
It's worth noting again here that the Lapis Philosophorum, now fused with the Symphogears, uses a heart motif.
A long time has passed since the theory of the heart being central to one's character has been disproven, but for "perfect life" could it actually be true?
There isn't anyone who knows everything.
