Sekirei was one anime to remember that followed along the lines of a cliche harem, but maintained it's own essence of originality. I loved the anime for it's humor and interesting characters, plus the action in here is superb. The ecchi feel in here is also flung around pretty easily amongst fight scenes. Problem is that the second season is taking too long to appear and the end of the first season was a little to cliff hang-ery-didy-didly-something.
ANYWAYS,I give this anime, SO FAR, 9/10. A great series worthy of continuation.
