Izumi is such a fantastic girl. I'm glad she managed to make it through without dying - she threw up a lot of flags in that last episode, but she managed to pull through anyway.
I especially liked the ending, where everyone realized what a terrible character Mei was, so Sakakibara decided to hook up with Izumi. The last scene, where the two of them kissed on the ferris wheel, looking down at the town was really romantic. I'm sure I wasn't the only one who teared up a little bit.
Izumi simply gets things done. She's a girl who has the lives of all of her classmates riding on her shoulders. She carries that weight and won't let it break her. She values the lives of other people - she cares about what happens to them, and as they start dying, the knowledge that she's partially responsible starts to build up on her shoulders. But does she give up? No way. She just keeps going along, trying not to crack under the pressure.
This comes as a contrast to Mei, who, when Sakakibara talked to her, decided to talk back, dooming her classmates to a horrible death. She even knew who the extra was all along, but rather than say anything, she decided to let even more people die. In the end, the only reason she bothered to go stop the extra is because her classmates finally decided to kill her; she might not care if other people died, but once her life was in danger, then she'll do something about it. She's selfish and a sociopath.
Izumi however, didn't hesitate. She went to kill the extra when she (thought) she knew who it was. She wasn't going to let anybody else die. She's smart, beautiful, nice and mature. And to top it all off, she's a god damned hero.
She's a fantastic girl. And I for one am very glad that, rather than dying a senseless death in the last episode, she instead survived and hooked up with Sakakibara. She earned that little slice of happiness.
