I have looked over some anime, that I think are suitable for showing.
I am aware that some of these may have been shown before. But as I have not been here since the starting of NAMsoc, I will post them, and you can comment to these, and maybe even suggest your own.

Mai-HiME:
Synopsis:
Thirteen girls, each with the ability to materialize "Elements" and summon metallic guardians called "Childs" have been brought to Fuuka Academy to battle mysterious creatures called Orphans. Each with a different personality and background, they must decide who they truly care about and why they fight.

I believe you have shown this one, so not much may be needed to be done with this one.

Mai-Otome:
Synopsis
Arika Yumemiya has traveled far in search of her goal: the prestigious Gualderobe Academy. This is the school where young girls are trained to become Otomes, protectors of royal leaders throughout the lands. Here, Arika makes plenty of friends, but some enemies know something about her past that she does not. Nevertheless, her spirit and determination will keep pushing her forward. --- Adapted from its predecessor, Mai-HiME, this series is not a direct sequel, but an alternate universe setting featuring some of the Mai-HiME cast (though with different personalities).

This is one I believe hasn't been shown, when I was talking to some members yestoday. So this one which is more than suitable, and it has some very funny and entertaining scenes, with a lot of humour.

Full Metal Alchemist Brotherhood:
Synopsis:
In this world, there exist people with special abilities to manipulate objects and transform one object into another. These people are known as alchemists. This process does come with a cost though, the basic law of alchemy states that in order to gain something you have to sacrifice something of the same value.

The main character is the famous alchemist Edward Elric - also known as the Fullmetal Alchemist - who almost lost his little brother, Alphonse, in an accident. Edward managed to contain his brother's soul in a large suit of armor. While he did manage to save his brother's life, he had to pay a great price himself.

To get back what they've lost, the brothers embark on a journey to find the Philosophers Stone that is said to amplify the powers of an alchemist enormously.

Fullmetal Alchemist: Brotherhood is a re-telling of the story from the manga point of view

This I feel is one that a fair few will like, but also will have a few haters (You can't cater for everyone). But it allows for some great laughs, and some cool scenes. I am sure many people would like to see it, however the season isn't finished yet, but has over 26 episodes already out. I think they are going for the same number as the previous FMA of 51(ish).


Disgaea:
Synopsis:
A comedy between demons and angels, with a little side of human. The main character is a demon boy that has been "asleep" for two years. He is awakened by an angel girl, who is sent to assassinate the demon boy's father. The series goes on to explain the awkward and comical friendship between a demon and an angel. Based on the popular strategy-tactics game.

We recently watched an episode or 2 during a random showing night. I think this is a brilliant short series, and definately worth watching, while making everyone laugh in the process. With only 12 episodes it will be over fast,so its most likely suitable to the last slot for showing.

Desert Punk:
Synopsis:
In the future, Japan is a wasteland. In the Great Kantou Desert, scattered humans eke out a living in the hot sand. Among them, a short-statured man they call "Sunabouzu" makes a living as a bounty hunter. Like a demon of the sand, he seems unbeatable. Yet, like all men, he has a particular weakness for the opposite sex...

We also saw an episode or 2 of this during a random showing night, I am uncertain as to wether or not people have seen all the episodes. But it is a very funny series, that I am sure will provide barrels of laughs. (Especially in the English dub)

Slayers NEXT:
Synopsis:
Lina, Gourry, Zelgadis, and Amelia coincidently meet up again and begin to search for the Clair Bible. During their search they run into a mysterious priest named Xelloss who seems to know a thing or two about the passages they're looking for, but he tends to get them into more trouble instead of out of it. Furthermore, they discover that the Monster race has plans of their own, and as it turns out, Lina and Company just might be a big part of their evil intentions.

Having watched the first season not so long back at NAMsoc, this would be a good one to view as many people enjoyed (as far as I could see) watching the original season. This is filled with so much comedy and entertainment, I am sure many people would love to watch it.
