Burai Kai

The Burai Kai (無頼改, Burai Kai) is an optimized version of the Type-10R Burai, and was created for the Japanese Liberation Front's elite unit, the Four Holy Swords. They make their first and only appearance during the Battle for Narita (episode).

Design and Specifications
The most distinctive change to the base Burai unit is the addition of a pair of long, trailing antennae mounted on the back of the head. Its performance is also upgraded, putting it about on par with the Holy Britannian Empire's elite RPI-209 Gloucester unit. Though capable of wielding the same weapons as the standard Burai, the Burai Kai's primary weapon is the Revolving Blade Sword (Katen Yaibatou), a chainsaw-bladed katana. Although proven to be an exceptional machine, all five Burai Kai units are abandoned following the Japanese Liberation Front's retreat during the Battle of Narita, and the Four Holy Swords eventually upgrade to the superior Type-3F Gekka.

Operational History
The Burai Kai make their only appearance during the Battle of Narita. With Tohdoh and the Four Holy Swords piloting them, they were a force to be reckoned with as they were able to destroy some of the Britannian Forces and hold off Cornelia's Royal Guard along with Guilford and Andreas Darlton. However, after Zero and the Black Knights retreated, they were forced to abandon the Burai Kai to retreat with the remaining survivors of the JLF.
