Dog Days
Dog Days hardly has any conflict and every character is abnormally nice for no apparent reason- yet I find myself strangely enthralled by the show. I don't understand.
You seem to like harems but based on those I'd recommend:
The World God Only Knows
Strike the Blood
Tokyo Ravens
Pandora Hearts
A Certain Scientific Railgun / A Certain Magical Index
The Legend of the Legendary Heroes
The Familiar of Zero
On another note, I just saw
this and might start watching MLP now.
