All About My Sister (オール・アバウト・マイ・シスター Ōru Abauto Mai Shisutā) is the 135th chapter of the Prison School manga, serialised in Weekly Young Magazine on May 12th, 2014 and published in tankobon format in Volume 14 on August 6th, 2014.


Chiyo is given a prison uniform too small, so she has taken the uniform of Meiko, which fails to cover her modesty fully. Mari ask Chiyo what happens to her, but is then angry at Kiyoshi's staring at Chiyo. He then notes that Chiyo is fretting over the scene she saw.
