this OVA is very Good, without going into a big story...
people protecting a planet, both good and bad guys fight in giant robots, kinda like the power rangers
but 1 million times better, the robots bleed when they get slashed in half (oil im guessing) lol , and they look like demons
. main characters are 2 badasses in a super coool robot.
To be Honest, my review makes it sound more Shit, but its Excellent... you have to download too
understand
