After Kallen and the Guren are captured during a battle with the Chinese Federation and turned over to Britannia, Lloyd Asplund is given access to the Guren. Much as Rakshata had done when creating the Shen Hu, Lloyd and Cécile Croomy got carried away in their modifications, which resulted in a machine that they believed no one was capable of piloting. In his care, it is upgraded into the Guren S.E.I.T.E.N. Eight Elements (紅蓮聖天八極式, Guren Seiten Hakkyokushiki?, lit. Crimson Lotus S.E.I.T.E.N. Eight Elements-Type). S.E.I.T.E.N. stands for Superlative Extruder Interlocked Technology Exclusive Nexus. For flight, it uses a four-feathered Energy Wing designed by Cécile. The system allows the Guren to move at blinding speeds, such that it appears to be little more than a pink blur in flight. The wings can also serve as cutting weapons. Additional armor is added on the legs and left arm, replacing the cannon, and the antenna have been extended and enlarged, making them appear to be giant ears. The chest armor is extended into the shape of a beak and a pair of green jewels featured prominently on the front. Its single chest-mounted Slash Harken is also gone, replaced by a pair of larger Slash Harkens mounted in its shoulder joints. Its radiant wave surger arm has also been upgraded significantly. It can be fired like a Slash Harken, and has a Harken Booster for controlled flight. The arm still functions when launched as such. Its original functions are retained and far more potent: the ordinary radiation burst can block a Hadron Cannon blast and the hand can crush energy shielding without the aid of the emitter. In addition, it can fire energy disks. The Guren's fork knife is also upgraded, having been retrofitted with MVS capability and made about twice as long. Its MVS (which is colored purple as opposed to the usual red) is evidently more potent than normal versions, as it can cut through the Lancelot Conquista's MVS swords.[42] It is damaged in battle against the Lancelot Albion, losing its head and both arms, but the chest survives intact. Artwork from the Last Picture Drama shows the Guren S.E.I.T.E.N rebuilt for reasons unknown
