... Angel Beats 3 had a rather fast development with people getting erased alrdy O.o 13 epis really does seem kinda short...

Iwasawa shows Yuri the new song that she'll be playing, which was a Ballad using a acoustic guitar but Yuri doesnt think that it'll serve as a good diversion for their upcoming operation and would prefer her to make a blast during the concert to obtain as much attention from the other students, AKA, NPCs during their next operation. The upcoming operation's aim was to infiltrate Angel's living area and to obtain any suspicious data. The others seemed to have went through the exact same operation before in the past and had failed but this time, Yuri declares that they have a genius hacker, Takeyama, to help them in the operation. Noda doesnt believe in that Takeyama guy and attempts to test him when Takeyama uses his "deadly" strategy, which was to recite the numbers of Pi (3.142....) into Noda's ears and got him squirming on the floor as his an idiot ._. Otonashi then went on to think of how the Angel's home looked like and when the others say that she's computer-controlled, for a moment, i tot i saw Howl's Moving Castle being potrayed... lol. After the meeting was dismissed, Otonashi then went practising with his pistol and later, while resting, bumps into Yui, who was pasting the posters of Iwasawa's band concert and then kept telling Otonashi about the details of the band etc. Otonashi manages to escape from her and sees Iwasawa practising with her band. She notices him and goes out to have a chat while taking a break. She tells him about her memories that she had, which she believes wasnt that bad as compared to Yuri's. Her parents were always quarreling and she doesnt have a place to hide at all in the home. When she encounters a band where the lead has a harsh life like her, she discovers that music could bring her sorrow away and she began to move into the music industry after picking up a guitar on the streets one day. She began to sing to her fullest until one day, an accident happened when her parents were quarreling, causing her to suffer a stroke and unable to speak and her life just ended like that. After she leaves, Otonashi could see that she seems to be also cursing on her life and he knows that just about anyone here is rebelling, maybe due to them feeling how unfair their own lives were. Angel then sees the posters of Iwasawa's band all over the noticeboard and takes them down and then mysteriously disappears. The operation then begins and Iwasawa places her acoustic guitar at the back while she prepares to lead the crowd with her songs and her electric guitar. Meanwhile, Yuri and the others managed to enter Angel's living area, which just turns out to be a normal room in a girl's dorm. Students are already flocking into the hall to listen to Iwasawa's songs and Takeyama begins to crack into Angel's computer. When he succeeds, Yuri sees a whole list of names of the students in the school and discovers as well that Angel is developing her own skills by herself, the harmonic guard skill does seem that she's able to split herself into two individuals. At the same time, Iwasawa's badn was suppressed by the teachers and she was playing her acoustic guitar with her own song after she managed to get it back from the teachers who wanted to throw it away. While she was singing, she realises that her life was to continue singing like this and that she'll be able to save someone else with her music and accepts her own life. The music suddenly dies down and Iwasawa disappears, leaving only her guitar behind. The operation ends and Yuri is troubled by the fact that Angel isnt getting her skills from elsewhere but was developing it by herself. The others were troubled too with Iwasawa's disappearance and they could only resolve that she was erased by the Angel. Otonashi then believes that following the school rules was the only way to get one erased.

Iwasawa's vocals were great too and the song she sang with her acoustic guitar was great too, and seems that if u somehow accept ur previous life and it is, u will disappear as well, AKA, being erased. thats what i tink for now, until they decides to explain it in the next few episodes, hopefully. and Yuri is now wondering whether fighting Angel is the right choice and it would be the worst case scenario if she could develop her own guard skills and diversions wouldnt be useful anymore if she decides to use harmonics.... the ED also had Iwasawa removed from the picture and i dun tink that she'll be the last one to disappear. Iwasawa's disappearance doesnt have too much impact emotionally, perhaps due to the little time she had on screen = less built up on the feel, would have been a rather large impact if it was like nearing the end of the series...
