Overman King Gainer
I haven't seen much of it yet, only like the first 7 episodes, so I won't say much. It looks half-decent. Have a look:
Its another mecha anime... and the mecha style is a little like Argento Soma. Also like Argento Soma, it was VERY hard for me to find any screen captures. Look at the tiny pic above. that's the BEST I could find.
But there's more to the show than the mecha. The story seems interesting. A bit confusing at first, but also cool. Its also lighthearted... but I get the feeling they are making us like the characters, so once we get attached, they can kill them off.
Annoying Character: Everyone besides Gain.
Bottom Line: "First watch the stuff I rated higher than this, then if you have time left..."
