Laevatein (レヴァンティン Revantin) is Signum's Armed Device.

It appears to have a personality but no programmed gender, and speaks German like other Ancient Belkan Devices.


Its name is a reference to Norse mythology, where Lævateinn was an invincible flaming sword wielded by the giant Surtr against the gods during Ragnarök (the end of the world).[1]

In the movie continuity, it is renamed as Laevatein Modified (レヴァンティン改 Revantin Kai) after the upgrade in Reflection. Such simple renaming may be due to the urgent and hence non-complex upgrade.

Laevatein is also titled the "Demon Blade of Flame" (炎の魔剣 Hono'o no Maken).


Laevatein is first introduced in the A's manga prologue and then featured in A's, StrikerS manga, StrikerS and Force.

After the Book of Darkness Incident, its structure has been optimized in the epilogue of A's manga. It has also been optimized a few times by Mariel Atenza during the period of StrikerS.[2]

In Force, Laevatein is the first traditional Device used against a Divider and the Eclipse. Although it is evenly matched with (if not superior to) Cypha's Divider-944, attacking her body directly causes significant damage to Laevatein, which is covered in cracks afterwards. As the battle continues and Cypha Reacts, she effortlessly shatters Laevatein near the hilt with her elbow and injures Signum. Laevatein is seen in action again in ch.20 during Signum's rehab spar with Thoma Avenir, with its functionality apparently fully restored.

Alternate continuitiesEdit

In the movie continuity, no significant change is noted in The MOVIE 2nd A's except for the minor changes in designs. In Reflection, Laevatein is urgently upgraded into Laevatein Modified by Mariel Atenza after being overpowered by Kyrie Florian's System Alter. It is equipped with an EM Cartridge System, and its form-change mechanism into Schlangeform is temporarily frozen.[3]

In the Brave Duel continuity, Laevatein's three active forms in The MOVIE 2nd A's are adapted as Signum's Brave Duel Device (see Laevatein), with extra designs added as additional forms (e.g. Laevatein II).


Forms Primary continuity Movie continuity
Laevatein (レヴァンティン Revantin)
Standby Form
Taiki Forumu)
Takes the form of a miniature sword with even bevels, hanging on Signum's neck-chain.

First seen in A's (ep.3).

Similar to the primary continuity, and its shape is now consistent with Schwertform.
Shuberuto Forumu,
Ger. "Sword Form")
Takes the form of a single-edged sword with a slightly-convex back bevel.

First seen in A's (ep.2).

The back of the blade is redesigned as straight without bevel, resembling a backsword without a knuckle guard at the hilt.
Shurange Forumu,
Ger. "Snake Form")
In this connected blade (連結刃 renketsu jin) form, Laevatein's blade separates into pieces connected by a moveable chain which can extend to assault or encircle opponents like a whip. It is mainly used for mid-range battles, and is useful at trapping or binding opponents.

First seen in A's (ep.5); aka Form Zwei in Riot Force 6.

Similar to the primary continuity without notable changes other than those in Schwertform.

Temporarily frozen during the urgent upgrade to Laevatein Modified in Reflection.

Bōgen Forumu,
Ger. "Bow Form")
Being the Full Drive of Laevatein, its sheath is combined to form a bow with two cartridge slots, which can charge the mana of two cartridges into one solid arrow for the aim of one-hit knockout. As the arrowhead has the same composition as Laevatein's blade, mana accumulated therein can be preserved for a short period of time even when the arrow is shot.[4]
While powerful, this form is awkward to use, leaving Signum defenseless for a few seconds as she draws and fires. Therefore Signum seldom uses it, even though this Full Drive form is available during the JS Incident in StrikerS.[2]

First seen in A's (ep.12); aka Form Drei in Riot Force 6.

Similar to the primary continuity with a minor change in design.
Laevatein Modified (レヴァンティン改 Revantin Kai)
Shuberuto Forumu,
Ger. "Sword Form")
N/A Its blade is strengthened by the all-time powering from cartridge, making it capable to cut through defenses of Formula system as well as armors of Mobile Shells.[3]
Bōgen Forumu,
Ger. "Bow Form")
N/A Installed with a mechanism to EM-accelerate strung arrows when shot, it becomes possible to shoot supersonic arrows.[3]

Laevatein's forms and functions are probably designed after the Angelg and Vysaga, two mechs piloted by Lamia Loveless in Super Robot Wars. Schwertform and Signum's general fighting style are themed after Vaisaga's sword, Schlangenform is themed for Lamia herself in reference to the mythological lamia, and Bogenform is themed after Angelg's bow, which can perform the Phantom Phoenix attack in the games much like Bogenform's Sturmfalken.


Upgrades Description
( Saya)
Laevatein's sheath is a part of the Device, serving as a mana-compressor for Schwertform and Schlangeform when the blade is pulled out from it. It can also be used to parry attacks (apparently surrounded by field-type defense) or form part of Bogenform.
Cartridge System Bolt-action-type Belkan Cartridge System like hunting rifles, with capacity of three cartridges.

In The Gears of Destiny, a special program cartridge named Wirbelwind (ヴィルベルヴィント Viruberu Vinto, Ger. "Whirlwind") is used. Its name is presumably a reference to the anti-aircraft gun Wirbelwind.
