Mad ( 気違い, Kichigai, Crazy, You can't help that. We're all mad here) Is Kristen's 1st solo photobook.
"You can't help that. We're all mad here" is a line by the Cheshire Cat from Alice in Wonderland. Kristen was confirmed to be a huge Alice in Wonderland fan, and thats how they decided on the title.
The photobook doesn't actually show ANY sign of insanity, it wasn't to ruin the image of Kristen either. Kristen said herself that she is pretty Mad (Crazy, Bonkers) herself.
It was released December 8, 2012.
