Yukako Kabei said this quote

Back then, living hadn't had any meaning. Every so often, without any warning or any real reason, he'd even caught himself thinking, 'Maybe I'll try dying.' He'd had one foot in the world of the dead, and yet the other foot had been chained to the world of the living, and he couldn't pull it out; he'd just looed on disinterestedly, sort of like it was all happening on the other side of some window, as the dull, vague world passed him by. Never making any more to walk out into it himself. Somewhere along the way, though, he'd stopped thinking about trying to die. He wondered when that had happened.
