It was true, what his note said. It seems like he was always around when he was needed. But now he's gone, body and soul. They cremated his body yesterday, depriving us of even the last vestiges of what was Urameshi Yuusuke. Of course, there are still memories, those haven't left, but they aren't as good as having the real, live Yuusuke here with us.
We were the ones who found him, the ones who had to tell everyone, his mother, his girlfriend, his rival, that he was dead. We were the ones, Hiei and I, who found him lying in the middle of his living room floor surrounded by a pool of his own blood and brain. And we were the ones who had to tell Atsuko that he was murdered, knowing how he really must have died. That was the worst of it, lying to his grieving mother.
It would have been enough, lying to Atsuko, but then Kuwabara recruited me to convince her that he wasn't going to come back. I broke her heart, and then I crushed her hope. But the worst thing of all, worse than finding Yuusuke, worse than losing him, worse than breaking Atsuko's heart and crushing her hope, was asking Hiei to use his Jagan to make her believe and understand that Yuusuke really isn't going to come back to life. That broke my heart.
We weren't there to see the disintegration. We left before Yuusuke's decent into despair, and that absence may have contributed to the speed of his demise. Surely if we had still been here the others would have come to us for protection as well. Instead, he was the only one left to take up our slack when the city came under attack. I can only imagine that there were more attacks after we left. The demons probably thought their victory more assured with the city being protected by one lone human. And he was left to fend off those attacks alone.
Of course Kuwabara would have helped him, or at least tried to help. Kuwabara cared very deeply for Yuusuke, though it may not have shown very much. Still, Kuwabara didn't have the power to defeat many of the demons that came after Yuusuke to prove their strength and I'm sure Kuwabara knew that he was no match for them. I'm also sure that knowledge wouldn't have kept him from trying.
I don't believe that Keiko will be coming to the funeral. She avoided coming to pay her respects before Yuusuke's body was cremated, claiming that she wouldn't be able to stand seeing him lying there as though he were merely sleeping, but I believe that there was another reason for her refusal. I think that she ceased to care about Yuusuke as soon as she began dating the boy at her college. I'm sure Yuusuke was devastated when she broke up with him. After all, he had loved her for far longer than I had known him. According to Kuwabara, it was the last straw, and I can only agree with that diagnosis.
