Following the establishment of the New United Nations Government, new and better airframes were commissioned as concerns grew over the growing independence of long distance emmigrant fleets and distant colony worlds. The VF-31A Kairos was first developed by S.M.S.' Ouroboros Branch in cooperation with several other companies including Surya Aerospace and the LAI Corporation, and based on the high performance prototype YF-30 Chronos. Research and design were provided by S.M.S. recruit Aisha Blanchette.
The VF-31A was then used as a base by Chaos Valkyrie Works to specialize in Vár Syndrome suppression through the use of song by the tactical music unit Walküre. The VF-31 Siegfried units were outfitted with an Inertia Store Converter and EG-01M/MP EX-Gear system. The ISC used a larger Fold Quartz crystal, enabling the use of the Fold Wave System similar to the YF-30 Chronos. The temporarily improved the fighter's output by resonating with its built-in quartz while amplifying and relaying the fold wave emitted from the singing voice of Walküre to its immediate surrounding.
In order for the fighter to correspond well to this system, the airframe structure, engine, were strengthened. In addition, various equipment relating to anti-Vár activities were added. Due to the large number of missions taking place within planetary gravity, the main wing is a forward-swept design so it can provide excellent mobility in atmosphere. The outer wing section is folded downward when landing or in moments of rapid acceleration.
Due to the its main purpose being to protect the Walküre and the general public, all Siegfried units are equipped with a melee weaponry and reduced explosive payload. The multipurpose container is equipped with an energy supply device for the "Cygnus" multi-drones and a sound projection unit that utilizes fold waves. The units are colored to look distinct and overtly military-based as its purpose is to be a panic-deterrent that may remind citizens of riot-control units, and also to inspire them that Walküre and Delta Flight have come to help.
The Siegfried variants usually are determined by differing head models, however the interiors can be unique depending on the pilot. They are equipped with a special AI called "ARIEL III" that provides auto-pilot capabilities that help during concert-based performance actions by each corresponding Walküre member.

The fighter's color scheme is a blue line under a white background with red accents and its head has dual camera eyes. The machine's number is designated 05 under Delta Flight. Chaos mechanics Makina Nakajima and Reina Prowler have adjusted the flight control system to Hayate, who prefers to have no AI system in his craft. In order for Hayate to operate the fighter without wearing a helmet, a device has been added to the back of the pilot's seat to automatically deploy the helmet attached to the EX-gear in case of an emergency.
