The 31st Suggestion: I Won't Increase (増えるーーのではなく, Fueru -- no de wa naku) is the thirty-first chapter of the series Medaka Box.


As Takachiho brags that he has figured out Medaka's ability, she remarks that she'll be embarrassed if he has. At Zenkichi's suggestion, Medaka tries to surpass Takachiho's reflexes with the Bunshin technique. This proves ineffective however, as he easily sees through the illusion, and breaks Medaka's arm. Zenkichi makes to join her side, but she orders him to stay back, insisting that the fight is one on one. She then reveals that she purposefully let Takachiho break her arm so that she could steal his flash drive. Takachiho then labels Medaka's ability as zero reflex; in that she has no reflexes at all. Hearing Takachiho's assessment of Medaka's lack of reflexes, Kikaijima thinks to herself that there is no other way to explain how Medaka can do the things she does. Zenkichi though is unimpressed, thinking to himself how Medaka never tried to keep that a secret. He worries though that Medaka is having too much trouble with the opponent on only the first floor, and that she is turning into an experiment for the Flask Plan. He continues to think to himself that the Thirteen Party are like the missing parts of Medaka's personality. Takachiho declares himself superior to Medaka, and then reveals that the flash drive she stole was just a fake. Medaka declares that she will prove that reflexes are not the best, and removes her shoes and socks. Zenkichi immediately orders Akune, Kikaijima, and the Tsushima twins to back up. Watching Medaka bounce from foot to foot, Takachiho notices that the sound of her feet coming down doesn't match with the actual point of contact. Before he can ponder any further, Medaka attacks him with her Kurokami Phantom, effectively striking his body before his muscles could react. Heavily wounded, Takachiho asks Medaka if she can move faster than the speed of light, before collapsing. Medaka explains that her bouncing up and down was to throw off Takachiho's timing, and she then attacked him when he blinked. Medaka is heavily wounded by the strain put on her body, and she accidentally destroyed the flash drive in the attack. She proclaims her victory, then collapses. Zenkichi runs to her side. He wonders why she would use such a dangerous move, remembering her behavior in middle school. He and the rest of the Student Council are horrified when Takachiho rises to his feet, and Medaka remains unmoving.
