Usagi Drop - No bunnies involved

First thing that sticks out is the artwork and animation at the start, it's very stylistic and unique, looks like it was painted with pastels and watercolour. Sadly that doesn't keep up and is only for the introduction or whatever but the artwork and animation is still good, backgrounds especially are very detailed and look beautiful. This is what I can only really describe as a slice of life anime with a pretty interesting and original story, some people might find it slow but it should end up as one of those stories that warms the heart.
Mayo Chiki - Primarily a comedy with some sprinkles of action (protagonist gets the crap beaten out of him) and probably some romance to come. The artwork and animation is very reminiscent of Ore no Imouto. I didn't really want to talk about the story now but someone pretending to be another gender in school for whatever reason, it's been done (Ouran High School Host Club, Maria Holic), the characters all seem somewhat clichéd as well (nose bleed when touched by opposite sex isn't all that different to breaking out in hives á la Maria Holic) but here's the thing, it really works. Yeah the plot isn't original but it's a different take on the thing, the characters may seem clichéd and archetypes but they're all very fun and the jokes are very funny. Recommend to fans of high school comedy anime.
No. 6 - "Futuristic" adventure anime best I could describe it. Artwork and animation is pretty good. Story is a little slow to start, characters have only just got established but it seems pretty interesting. It may turn into something that Shirai will like
Uta no Prince-sama - Slapstick romantic comedy adapted from a PSP game sums it up pretty well

Shoujo-anime so the art-style is very befitting of one, girls are all pretty with big eyes but not large breasts (although the heroine isn't flat as you'd expect) and all the boys are "bishie". Something that kinda bugs me is the heroine's eyes, yellow with green pupils, WTF?

It is pretty funny but not quite laugh out loud funny as say Fruits Basket or Ouran High School Host Club. Another thing to notice is there's a lot of famous/recognisable seiyuu in this anime and I was surprised at how good Kira/Yagami Light is at singing

If you like titles such as Fruits Basket, Ouran, Kaichou wa Maid-sama, etc. you'll probably enjoy this one.
Mawaru Penguin Drum - This one doesn't seem to be mentioned on that poster. I'm not really sure how to classify this, my guess would be at a cross between fantasy and sci-fi with a dash of comedy. The art-style reminds me of Honey & Clover a bit but the backgrounds are really well done with a lot of detail, it's also quite stylistic with certain elements and some good use of CG. The poop really hits the fan at the end of the first episode with some psychedelic animation. It might not be for you but I strongly advise checking it out anyways, it's totally unique there isn't another anime quite like it.
Blood C - It's been a while since I saw Blood The Last Vampire but I can't remember it being anything like this. The art-style is very shoujo-manga, as in all the characters are tall and thin, though there is a fair amount of boobage. It also starts off much the same way as a shoujo-manga would, the heroine is a bit of a ditz, she has a group of friends etc. introduced and there's some sprinkles of comedy thrown in to lighten the mood. Have to wait until the end of the episode to watch a fight with some weird thing that looks nothing like a vampire but then again I don't remember what the "vampires" looked like originally. Still it doesn't put me off the anime though there are probably others that would be disappointed hoping for it to be darker and more gritty. Give it a shot, I'm sure the story will get more interesting and darker.
