Inside a background where Hibiki appears in SD form in her Gear.

"Kinoko Lesson!" Hibiki said as she went to a classroom and sat down.

"Today's Item we present is this!" Hibiki presented.

As the monitor showed the Armed Gear with the Japanese language.

"An armor-type weapon constructed using the energy of fragments of holy relics, or the name of that system. It is also the name of the "FG-type Kaiten special armor" created based on the "Sakurai theory" advocated by Ryoko Sakurai. The power of the holy relic that remains in the fragment is activated by a wave of a specific amplitude (=song) by the suitor, and after being reduced to energy, it is reconfigured into the shape of the armor. A fit person who wears Symphogear is called a wearer. The characteristics that the gear brings to the wearer are increased physical function, a barrier coating function that protects against noise erosion due to sonic vibration impact, and furthermore, tuning the state of noise and forcibly fixing it under the physical laws of the human world to make attacks effective. and invalidation of the phase difference barrier. It is the only weapon that can counter noise from these functions, and has the alias of "anti-noise protector". In addition, the defensive performance that protects the wearer's body is extremely high, and it is possible not only to mitigate impacts, but also to operate in outer space, break through the atmosphere, and re-enter, so there is no place where it can not operate. The fragment of the holy relic is stored as a core inside a pendant that looks like a long red crystal worn by the wearer, and the pendant has a microphone function and activated energy for singing. [35][36]. Reconstruction into gears is initiated by the relic's fragment sensing an activation song called a chant[37]. After wearing the gear, the pendant part transforms and is placed on the wearer's chest, and the sound collection microphone function for singing is used as it is. After wearing it, it resonates and resonates with the wearer's fighting spirit to generate a melody, and the wearer sings along with it to increase its power. Therefore, the wearer needs to fight while singing, and if the singing is interrupted due to damage, etc., the power will temporarily weaken. However, since there is a gap between humans and the holy relics that make up the gears, there is a price to pay for the energy load released from the gears to undermine the wearer even if they are fit. A total of 301,655,722 locks are applied to gears to reduce this load, also known as "backfire", which are systematically and gradually unlocked according to the individual skill and tactics of the wearer. It is a mechanism that changes the shape and function of the gear by being pressed. Because it is the result of heretical technology, its existence is completely concealed by the Japanese government, just like other relics [Note 37]. It is believed that a Symphogear's combat ability is largely determined not by the wearer's physical strength or motor nerves, but rather by their mentality. Therefore, the training of the wearers is focused on cultivating self-belief and "confidence", and there is a menu prepared for each. In fact, these steady efforts have improved the suitability coefficient of each wearer and the corresponding combat ability, and the effect has been proven [38]. In the third period, all units are destroyed by Arca Noise and Mika. Due to the death of Ryoko, the developer, it should have been impossible to restore, but Elfnein, who has knowledge of alchemy, including patchwork technology for holy relics, planned Project Ignite, and the project succeeded in strengthening and repairing. In addition to repairing the damaged Symphogear system, the barrier field was adjusted to increase output and attenuate the decomposition effect of anatomical organs, and the Ignite module (described later) increased combat power. "Ignite" is a useful decisive battle function and has achieved many battle results, but in the final episode of the 4th season, due to the rebuilding at the time of Adam's decisive battle, the load of Dainsleif, which is the key to the function, is reduced by diverting the energy of Lapis Philosophicus. It was lost by incinerating it instead of shouldering it, but instead, it acquired a new decisive battle function, Amalgam, by incorporating the characteristics of Lapis's Faustrobe…" Hibiki said as she panted and layed down.

"And also figure out what is about us!" Hibiki said as she waved with a smile. "See you next time!"
