I can recommend you Kill la Kill - if you don't mind explicit fanservice. The first five episodes are nice and dandy but then -blam!- begins to hit the fan, with plot twists every single time and hype to watch the next episode. Imagine [i]Tengen Toppa Gurren Lagann[/i] having a child with [i]Panty and Stocking with Garterbelt[/i], that is now in its rebellious teenage years - That's KlaK.
