Kaworu didn’t die back then on that mission with the electronic collar — only Shinji did. He took that collar. In the end, Shinji died; he didn’t want Kaworu to die, because Shinji loved Kaworu too. When Kaworu saw Shinji’s death... he was furious. He killed all humans and destroyed the entire planet. He loved Shinji — truly loved him, with all his heart. Shinji was the one who saw the real Kaworu, not just his outer shell. Since Kaworu was the last, the 17th Angel, he possessed great power — humanity couldn’t withstand it, and they perished. And eventually, Kaworu died as well.

Shinji opened his eyes to the sound of his alarm clock. He got up, washed, got dressed, and had breakfast. He fed the penguin, left breakfast for Misato, and went to school. Shinji pilots Evangelion Unit-01. Recently, he defeated the Fifth Angel without any training, even though he arrived in Tokyo just two weeks ago. Shinji sat at his desk, and in the same class was Rei, who pilots Evangelion Unit-00. A new student entered the classroom — his name was “Nagisa Kaworu.” He greeted everyone and sat next to Shinji. The lesson began; the whole time, Kaworu looked at the board, listening attentively to everything the teacher said. Shinji listened too. During the break, as usual, Shinji sat alone — then Kaworu approached him. "Hi, Shinji, let’s be friends?" Kaworu said with a kind and loving smile.
