The 155th Suggestion: For the Sake of Zenkichi (善吉のために, Zenkichi no Tameni) is the one hundred and fifty-fifth chapter of the series Medaka Box.


The group makes their way to another area to start the final round. Momozono asks Medaka which two of the four available hostages she wants released. Medaka requests Ajimu and Hanten, feeling as though Momozono wanted her to chose Shiranui and Tsurubami. Ajimu tells Medaka that Momozono wanted her to choose them, since they were already close to escaping themselves, causing Medaka to ask if Ajimu cannot just thank her. As Ajimu prepares to end everything, Medaka stops her, stating that she desires to fight for Zenkichi's sake. Ajimu chastises her for giving in to her emotions, but acquiesces. Momozono and the other two suitors stand together in the new area, opposite Medaka, as the rules of the game are laid out. Medaka adds the rule that each player must submit their syllable in exactly an hour, or they are disqualified. Momozono adds one final stipulation in order to prevent any violence after the game ends. If Medaka wins, Momozono shall cut out her tongue (and her style). If Momozono wins, Medaka must gouge out her own eyes. Momozono then begins the game with the syllable "Ri".
