So I finally watched the whole serie, 39 episodes. I watched the american version, who is slightly different from the japanese version with the introduction of Hariel, the Dark Warlord / Ronin warrior combo that wore the white armor. He was introduced in the dubbing so peoples wouldn't be too confused with the arrival of the white armor in the serie.
While the serie was planned to be 39 episodes long from the start as I read, there is a lot of dialogs that seems a bit weird. But since the original lines didn't included Hariel it makes a lot more sense. It is likely some of the original text that didn't worked well with the dubbed version. Otherwise, the serie isn't as good as I remembered it, and while the armors are quite cool, all too often it is a Deux Es Machina that saves the warriors at the end. It is so dissapointing. The two normal humans really were too much at times, especially the child. Many plots are unfinished, Ryo is so much here that you have barely any screentime for the others warriors (the Strata one is the one suffering the most).
