Deadman Wonderland Vol 13

Framed for the brutal murders of his classmates by the mysterious Red Man, middle school student Ganta Igarashi finds himself sentenced to death and sent to the bizarre and fatal theme park/prison that has risen from the ruins of the Great Tokyo Earthquake-a hell on earth known as "Deadman Wonderland."
Ganta and Shiro finally face off against each other inside a collapsing Deadman Wonderland. Shiro speaks of her past and how she's been wishing for Ganta to kill her. Ganta asks her why she killed his friends, but Shiro just pleads with him to make her wish come true. In the end, Ganta cannot bring himself to do it, and so the final battle begins.
