First Impressions

Naomi Ritsuko is a 16 year old thief and hacker. She is also a killer...when she's moody. She also kept escaping (via hacking and stealing keys) prisons and the final option was to resort to Nanba prison. Will she escape the prison or get caught up with her new friends? I only said it was mature due to cursing but i'd say it's 13 and up
