"Prison School" chapter 207 is already available for reading through Manga Park. The chapter continues the battle story arc between the Official Student Council and the Underground Student Council. Before any predictions on the upcoming chapters in the popular manga, here's a brief recap on the story.
Kate learned through Mari that the Underground Student Council (USC) is using Kiyoshi to drive their supporters away and gain the advantage. Kate decides to bring out her counter attack that would limit Kiyoshi's power. On the other hand, Kiyoshi is feeling a bit weak and needs some assistance from the group.
The combination of taunts and sexy promises from the other group as well as the lack of service from the USC, Kiyoshi is thinking about changing sides. Mari orders Meiko to physically restrain him from switching sides and inadvertently grab hold of his manhood. Kiyoshi returns to his original form. Hana, realizing that she hasn't done anything significant in the battle decided to do something herself. The chapter ends with Hana kicking Kiyoshi from behind so that she could remove his underwear.
Although Kiyoshi has the limelight in the past few chapters, it is probably high time for the protagonist to get some backup. The backup may not be the same as Kiyoshi's technique but it could be some other form of attack. Mari is only asking Kiyoshi for a victory without using his hands so others can definitely aid Kiyoshi in one way or the other.
Shencomics recently released the Korean scanlations of the upcoming chapter. Based on the images, Hana has successfully taken off Kiyoshi's underwear but it seems that Kiyoshi goes through an out of body experience where he sees everyone frozen. PSninja on Reddit predicts that Kate will have to fight back in the future chapters or else Kiyoshi will lead the Underground School Council to a complete victory.
