* EasyAmnesia: The chairman loses his memory after an incident with a waterfall. He does avert IdentityAmnesia however, as apparently nothing can make him lose his love of asses.

* {{SexyDiscretionShot}}/{{SomethingElseAlsoRises}}: [[spoiler: As things between Mari and Keito start to heat up while making out on Keito's bed, the manga cuts to an image of a double ouroboros- two snakes biting each other's tails. As later panels reveal, yep, they did.]]

** Hana wants revenge on Kiyoshi for seeing her pee outside. Then double revenge for both that and what happened when her previous attempt at revenge went wrong. Then triple revenge when ''that'' backfired. You get the idea.

* WrongGenreSavvy: Chiyo has a tendency to get the wrong end of the stick where tropes are concerned, mistaking a GreatEscape as a SurpriseParty, Hana's quest for {{Revenge}} as TrainingFromHell in the mountains and [[NakedPeopleTrappedOutside Hana's panties in Kiyoshi's room]] as Gakuto [[WholesomeCrossdresser cross-dressing.]]

* ExcrementStatement: In the nurses room Hana forces Kiyoshi to lie on stomach on a bed so she can urinate on him as payback . She doesn't get a chance to do it since she has to go under the bed with him to hide from Chiyo who just walked in.

* WrongGenreSavvy: Chiyo has a tendency to get the wrong end of the stick where tropes are concerned, mistaking a GreatEscape as a SurpriseParty and Hana's quest for {{Revenge}} as TrainingFromHell in the mountains.

* FreudianSlip: Mari is quick to reassure Chiyo that she hasn't let anyone put so much as a finger in her. '''On her!'''

** This is subverted with Gakuto. After a string of accidents (purposefully done) that ended with him pulling down Mari's skirt. Gakuto goes to Meiko to atone. She [[GloveSnap puts on a glove]], and pulls an object from a drawer that's ''[[{{Pixellation}} mosaiced out]]''. It's later reveal that it was just hair clippers. Gakuto's atonement is he had his hair shaved.

* [[{{Dominatrix}} Dominatrix]]: Risa tries to be Andre's Dom since Meiko, after the fire incident, is incapable of hurting him. She's having little success since she not as wicked as Meiko so all of her abuse ends up being too soft for Andre.

* ShoutOut: Chapter 172 is titled [[Film/{{Skyfall}} Sky Fall]].

* InevitableWaterfall: [[spoiler The Chairman suffers one after braving a river to save a puppy.]]

* IronicEcho: There's a lot emphasis on the panel where Keito calls Mari a "base woman" for her hypocrisy (see MoralMyopia). The irony of that insult is revealed in a later chapter that's a flashback. When the two were in elementary school Mari had used the very same insult on Keito in front of their entire class for making fun of Meiko in a childish manner.

* FriendToBugs: Jo like insects, even owning an ant farm with individually named ants.

* {{Gaslighting}}: [[spoiler: Kiyoshi]] eventually concludes that the best method of distracting Risa is to drive her steadily insane with various perverted acts.

* {{SexyDiscretionShot}}/{{SomethingElseAlsoRises}}: [[spoiler: As things between Mari and Keito start to heat up while making out on Keito's bed, the manga cuts to an image of a double ouroboros- two snakes biting each others tails. Yep.]]

* {{Gaslighting}}: [[spoiler: Kiyoshi's]] chosen method of distracting Risa is basically to drive her steadily nuts with various perverted acts.

** Kiyoshi essentially [[Gaslighting gaslights]] Risa with perversion to make her guard slip.

** Mari on Keito. [[spoiler: Mari manages to break out of prison by smuggling in a pair of handcuffs under the assumption that a paranoid Keito would bind the two girls together to make absolutely certain Mari couldn't escape from her sight, then making it look like Keito's room had been broken into, thus forcing Keito to take Mari with her when she went to investigate. Had Keito not cuffed Mari to herself the plan would have failed, but (double spoiler) [[note]]Mari correctly guessed that Keito wouldn't pass up the opportunity to be chained to her crush, later compounded when she falls for Mari's HoneyTrap and has sex with her on camera![[/note]] ]]

** Then both Mari and Kiyoshi again with [[spoiler: suggestive footage of them taken during a SuckOutThePoison situation that Keito engineered for that very purpose, which is later countered by Mari blackmailing her right back into a stalemate.]]

* [[HoneyTrap: Mari sets one up on Keito to counter her own blackmail pics.]]

* {{SexyDiscretionShot}}/{{SomethingElseAlsoRises}}: [[spoiler: [[http://raw.senmanga.com/Prison_School/164/3 Well... Uh...]]]] (Warning, NSFW pages before and after the link.)

* Reverse Mole: [[spoiler: Hana fakes defection to the Aboveground Student Council to act as Mari's mole.]]

* SexyDiscretionShot/SomethingElseAlsoRises: [[spoiler: [[http://raw.senmanga.com/Prison_School/164/4 Well... Uh...]]]] (Warning, NSFW pages immediately before and after the link.)

** And both Mari and Kiyoshi again with [[spoiler: suggestive footage of them taken during a SuckOutThePoison situation that Keito engineered for that very purpose.]]

** Mari on Keito. [[spoiler: Mari manages to break out of prison by smuggling in a pair of handcuffs under the assumption that a paranoid Keito would bind the two girls together to make absolutely certain Mari couldn't escape from her sight, then making it look like Keito's room had been broken into, thus forcing Keito to take Mari with her when she went to investigate.
