The 2nd OVA isn't much better than the first one.
The story is mediocre, basically it's about a very cool shirtless super-powered guy who meets Terminator and gets to drive the brother of KITT. This time there are less nude women but more explosions. Explosions are cool though.
The best about this OVA is the ending song which is gorgeous with the rough sounding voice. Second best is the character design which looks nice.
