Nanba Prison, the world's most formidable prison, the location is unknown but that is not important. What's important is, inmate number 1314, Sen Michiyo, will now live in Nanba Prison where inmates are predominantly male and both prisoners and guards are far from normal. She has escaped many prisons in the past but she's having issues to get out of this one?! She can't work out why she's unable to escape...perhaps fate wanted her to stay behind and find something here? What will her story become by staying in this inescapable prison? Collaboration with my dear friend, Fumi-chan!
