Frame Gears

Frame Gears (フレームギア) (usually abbreviated as FG) are single-piloted giant mobile robot which were designed by Regina Babylon and constructed by High Rosetta and Fred Monica to combat the Fraze. Currently, all development is centered at Brunhild Dukedom under supervision of Touya Mochizuki.

Old Design
Frame Gears were developed by Regina Babylon during the war between human and the Fraze 5000 years ago. The Frame Gears were planned to be used as the ultimate weapon for winning the battle. However, when the Frame Gears were ready to be used, the Fraze suddenly disappeared and the plan for mass-produce the Frame Gear never brought to fruition. At that time, only 7 Frame Gears, which model are different from each other, were completely manufactured. After the war, all old generation Frame Gears were stored in the Hangar.

This model requires special fuel called ether liquid. The liquid is extracted from ether ore, which actually an older term of magic stone. The liquid can be manufactured in the Laboratory and the Alchemy Building but the Alchemy Building's ether liquid quality is lower than the Laboratory's. The liquid will act as the Gear nerve system which will synchronizing the pilot's magic power with the robot's body. A 500 mL ether liquid is enough to fuel the Frame Gear for 1 month.

Frame Gear can be piloted by almost anyone, although the pilot's compatibility with the air frame and its magic power might influence the control. The Gears are controlled from the cockpit on the chest of the robot. The cockpit is protected with several protection magic which mitigate external physical damage from the cockpit. The foot movement, such as walking, must be controlled using foot-levers under the pilot's feet on the cockpit while upper-body movement is controlled using the control stick but other minutiae movement -such as finger movement, neck movement, and waist movement- can be controlled by thought only. For safety measurement, each Frame Gear can be remotely shut down using the emergency stop function from Touya Mochizuki's smartphone. The pilot is able to draw his/her magic spell using the Frame Gear after pouring in his/her magic power through the control stick.

The production and development of Frame Gear is continued by Touya Mochizuki with High Rosetta and Fred Monica work as the contractor and manufacturer of the Frame Gear. Mini autonomous golems from the Warehouse usually employed to help the process of repairing and production of the Frame Gear. Touya also assigned 10 units of 30-cm mini robot from the Rampart for helping Rosetta and Monica with the production process. According to Rosetta, the process for manufacturing the simplest Frame Gear will take a whole day and require a huge amount of material. Through Strand Trading Company, Touya manages to get metal material such as iron, copper, silver, mithril, orichalcum, and hihiirokane for half of total profit he get from his product royalty. The orichalcum is used for the power reactor part. The first Frame Gear produced was Chevalier, the gray heavy knight which excel in defense. Night Baron, the black knight, is then produced simultaneously with the Chevalier which excel in offence. Later, Frame Gear that excel in mobility was manufactured and called Dragoon, the red knight. Chevalier, Night Baron, and Dragoon are based on the old design of the Frame Gear.

New Design
The new design which was envision by Regina Babylon, adds major upgrade from the old design and customizability for the Frame Gear. However, this design never been created at Regina Babylon's era and the blueprint for this design was then stored in the Warehouse. Later, this design was used by Touya Mochizuki for creating exclusive frame gears with help from High Rosetta and Fred Monica.

The requirement of ether liquid has been removed in this design. The usage of crystal material as the power core enables the Frame Gear to accumulate magic power through the light or the atmosphere. The old design also has problem with the magic amplification which might break the frame, this issue has been resolved in the newer generation.

Common Configuration
Each Frame Gear records its battle log and the tuning data of the pilot. This mechanism will make the Frame Gear more synchronized with the pilot as the flight time increasing. However, it also makes the Frame Gear difficult to be repaired as each Frame Gear has to be fine-tuned according to its existing data. It is also impossible to only replace the exterior of the Frame Gear while still using the old internal system as restoring, linking, and adjusting both of system is laborious.

Because of the arduous system for controlling and maneuvering the Frame Gear, High Rosetta created a training pod for the Frame Gear. The first installment was 8 units of training pod in the playroom of Brunhild Dukedom. After introducing the Frame Gear to the Western Alliance, Touya Mochizuki gave 6 units of training pod to each alliance member which were Kingdom of Belfast, Regulus Empire, Kingdom of Mismede, Rifurisu Empire, Ramisshu Holy Kingdom, and Kingdom of Lihnea.

Earlier, because there is no communication system built in the Frame Gear, communication was established using the summoned divine beasts, Kougyoku. Later, Fred Monica installed communication device which connecting one Frame Gear with the other and also the command center. The Frame Gear also has a private communication channel and external speaker installed.

Trivia

 * The material for building the Frame Gear is combination of actual and fictional substances such as mithril -a fictional metal-, orichalchum -a Greek-Roman mythological metal-, and hihiirokane (ヒヒイロカネ) -a Japanese mythological metal alloy.
