Tachibana Kanade: We need a reason for this? She's the catalyst for everything, almost.
Nakamura Yuri: For being the first to realise what had happened. In spite of her thinking everyone's 'stupid', she's pretty smart, loving (obviously) and courageous. As was said on her graduation certificate: "For showing the greatest dedication in the Battlefront"
Otonashi Yuzuru: He moved us along. And for once, he was the only sane one too. He made sure everyone had left before he did, almost putting him with the same qualities of Yuri, just with some more romance added.
