This anime has cute girls in it, and interesting monsters and fights. I liked it so much I made a wiki for it in 2011 but sort of stalled on ep 10 The fansubs that exist are nice and small and good for watching on low-res computers that can't handle all that 1080 stuff coming out nowadays. There's a neat contrast between the 3 teachers who become heroes and the 3 students who encounter monsters and need to be saved. They represent the change in responsibility. Pink for the woman is a little stereotypical following after Beast King GoLion (pretty sure Voltron preceded power rangers) but it's manageable.
