That I couldn’t stand Ikkitousen. I mean, damn, the girls are gorgeous. It would be the harem to die for, if it had been that kind of show.
No mere thumbnail will do justice for this wallpaper, so it will blow the formatting — and I warn you, it’s emphatically NSFW.
NSFW: 
You HAVE seen the “Dragon Destiny” omakes, haven’t you?
Didn’t know they existed. Watched about 15 minutes of the first episode, ran from the room whimpering. It’s just too close to (the so-called sport of) wrestling, even if the girls are gorgeous.
The omakes have nothing to do with the main story. It’s all the “good” girls visiting an onsen. It includes all the girls in your poster except the one on the far right, who first appears in “Great Guardians”.

Then there’s the Ikkitousen Great Guardians omakes, which are little pieces of hell all their own… fortunately, you can just head over to The Pond to see the posts I put up about them, without actually having to suffer like I did.
