we get a lot of swords in this episode, as Gokai Blue (is that right?) has to practice to beat the weekly kaijin. the episode starts with the team trying to make their robot turn into other robots (like Battle Fever J's) but failing. the onlookers are all less than impressed with the failure as well, putting their cell phones down.
then we get to the badguys sending their weekly guy down to terrorize the Earth. he has a special sword technique and apparently that's Blue's specialty.
it's a pretty good episode. no special guest star, but Gekiranger makes an appearance so that made me happy.
