Angel Beats' 1st episode headed off to quite a promising start, with both action and small character developments being placed into the 1st episode.

The main male protagonist, Otonashi, wakes up and has no memories of how he had ended up in his current position and place. The female protagonist, Yuri, then tells him about the fact that the world he is in now is the afterlife and with him existing here, he must have died in the living world. Otonashi does not really believe in what she says. Yuri continues by telling him that he would be erased by God if he does not rebel in this world and the only enemy of them was the Angel, which she points out at a girl in the middle of the field. Otonashi asks Yuri if the gun of hers was a real one and she tells him to take whatever he sees as it is and asks him to enlist into their battlefront, which is also called the Class 3S, as seen on their uniform. Otonashi however decides to go to the girl whom they call Angel and asks her of her identity. The girl replies him that she is merely the student council president and that there are no hospitals around as everyone is already dead when Otonashi suggested to get himself into a hospital due to his amnesia. Otonashi doesn't believe her words as well and asks her to prove that he was already dead and would not die again. Immediately, a blade appears on her right hand and she stabs it into Otonashi's heart. When Otonashi wakes up again, he sees a blood-drenched cloth beside him whereas his body was clearly fine and gets scared. Another person comes into the room and slashes Otonashi all around as he had not went according to the requests of Yuri, leaving Otonashi in a pool of blood but was clearly unharmed. Otonashi later ends up in the meeting room of the 3S battlefront (naming their battlefront this name would be easier since they're like constantly changing it) where Yuri asks him again to join them to prevent himself from being erased and reincarnated into another being that is not human. Otonashi agrees and joins the battlefront and Yuri took the chance to introduce the members that were currently in the room. Otonashi later learns from Yuri that the other students who are following the rules will be erased and that was why they had decided to rebel and continue living as humans in this world. In the night, Yuri decides to carry out Operation Tornado where the aim was to steal the lunch coupons of the students in the school. Otonashi was handed a pistol and was set to guard one of the posts in the school where they will open fire on the Angel if anyone spotted her. Iwasawa and her band, who are also members of the 3S battlefront then distracted the students by playing one of their songs in the dining hall, creating a concert atmosphere within the students themselves. The Angel seems to have spotted their actions and had advanced through Otonashi's guard post. He opens fire at her, knowing that he would be 'killed' again if he does not act fast but the wound he delivers was not able to stop her from advancing. The other members of the 3S battlefront covered Otonashi and opened fire at the Angel but the Distortion protection that the Angel had activated had prevented any serious damaged from being dealt. The electric fans in the dining hall was then turned on and blew the food coupons away from the students, who are singing along with the band, resulting in a successful operation. The members then had their food at the dining hall again and Otonashi starts to wonder if their actions are justified but it was too soon for him to think about it now as he does not remember anything about his past at all and that is his current priority.

Most of the scenes in the PVs have already appeared in the 1st episode, including the concert scene and the stabbing of Otonashi by the Angel. i really had thought that that would be at the climax of the series or some sort but it could spur on a further in depth development of the story and a more wonderful KEY-styled climax and ending, which i hope there is. The little bits of humorous antics did lightened the atmosphere of the series and it doesnt seem that their enemy was just simply the Angel and could probably lead to more mysteries and maybe would reveal the memories of Otonashi and the past selves of the other characters... got a feeling that Yuri and Otonashi could have some relationship in the real world O.o anyway, it really had a promising start and hopefully it'll last through the entire series :)

BTW, The World God Only Knows' anime series production has already been confirmed (i tink im a little late in this) and it COULD become a successor for Baka to Test in the hilarious antics and its 'romantic' scenes... shall look forward to it :D
