Monster Zero (怪獣大戦争 Kaijuu dai Sensou) is the 212th chapter of the Prison School manga, serialised in Weekly Young Magazine on April 11th, 2016.


Though the other boys and Hana assume that Mari's intention is to revive the outward appearance of Meiko's Vice-President persona with her last carbonated bottle, she uses it to temporarily impair Andre's vision against the ASC cavalry team's protests. The shocked Gakuto deduces Mari's underhanded intention to prevent Andre's movement while Risa and Kate accuse Mari of cheating. The comical failure of Mari to realise the failure of her ploy for Kate's headband is to her embarrassment when she lifts her hand to barely reach Andre's waist. When the blinded Andre is revealed to have extreme co-ordination with Risa and the capability to execute attacks while maintaining his balance, the USC cavalry team is forced to pull numerous evasive retreats using Kiyoshi and Hana's reflexes. The second attempt to blind Andre fails when the bottle lands in Meiko's mouth, breaking Andre's bondage by Risa and prompting his approach of Meiko.



  • The chapter title is a cultural reference to Japanese science fiction horror film Monster Zero.
