An optimized version of the Type-10R Burai, the Burai Kai is created for the Japanese Liberation
Front's elite unit, the Four Holy Swords. 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 Britannia 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 brake blade, 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.
