It has been years since I first read Shuumatsu no Laughter, and every couple of months or so I would always re-read it again just to immerse myself in the main characters' turmoils and the theme of prejudice and fear.
This is an excellent read. A shame it is short, but I think because it's so short that it's easy to digest and re-read again.
And at the end of the day, I can just laugh it up as something precious in my catalog.
