^ just wait until you read the part about sachiko
I finished watching chuunibyou and I liked it and sorta reminded me of denpa ona where the erio thinks she's and alien but this girl thinks she has superpowers. second half was more interesting since it added a bit of drama
don't worry about the eye patch it's nothing serious
Instead of watching btooom I would read the manga(from mangafox) since the anime was rushed and less graphic than the manga Instead go pick up "Another" anime it's a good alternative to dusk maiden of amnesia if you plan to read that instead.
EDIT
if you managed to enjoy something lie dakara then I'm sure you'll like "Sword art online" it has cool male lead,cute girls, and the setting is similar to ZnT
