If terra is still in the world, it will not be a problem, but the world is sucking out your energy. Without her, he says, you won't have the energy to stay in this world. He says that even if he has to return to the underworld, he's not giving up his dream. He hopes that when he comes back, the world will still be as beautiful as it was when he first met yuji. He wonders why all reapers are like this. They just think and say whatever they want. He wants to stay alive because he wants to be with the people he loves, but he doesn't want to sacrifice himself for the sake of his love. He just wants to live for his own happiness.
