Expulsion is an elimination method used to eliminate rivals non-lethally.
The description on the Schemes menu is: "This scheme will end with your rival being expelled."
Ayano Aishi can expel students by framing them for or witnessing them breaking school rules and reporting them to Genka Kunahito, the guidance counselor. Currently, this elimination method can only be used on the Rivals or Delinquents. The player have to report it before After-Class time.
Frame for Panty Shots (Monday)
On Monday, the player must fill a bucket with water, place it over a doorway, and lure Osana through that door. Once Osana is drenched in water, the player must follow her to the shower room to steal her phone, take a panty shot with the stolen phone and place the phone on Osana's desk. After that, the player must wait for Osana to find her phone, report her to the guidance counselor, and attend class.
Frame for Theft (Tuesday)
On Tuesday, previously, the player must steal Sakyu Basu's ring while she's eating lunch. As of May 3rd 2022, the player must splash Sakyu with water, and steal her ring undetected in the shower room and place the ring in Osana's bag, which is at her desk. After that, the player must report Osana to the guidance counselor and attend class.
After Osana is framed for stealing Sakyu's ring, the guidance counselor will return it to Sakyu at the end of the day.
If Ayano does not report Osana to the guidance counselor after putting Sakyu's ring in her bag, Osana will discover it and return it to Sakyu, who will never bring her ring to school again. This will cause the expulsion process fail.
Frame for Smoking (Wednesday)
On Wednesday, the player must obtain a pack of cigarettes before class. These can be found in the convenience store in Buraza Town, in the faculty room on Kaho Kanokogi's desk, or in Info-chan's "Drops" menu. Once the player has cigarettes, they must be placed in Osana's bag, which is at her desk. After that, the player needs to report her to the guidance counselor. The final step is to attend class as usual.
Frame for Vandalism (Thursday)
On Thursday, the player must find a screwdriver, sabotage the yellow vending machine in the cafeteria, buy a salty snack from the red vending machine, and pick it up off the ground. After that, the player must go to the school plaza to give the salty snack to Osana, follow her to the yellow vending machine to take a picture when she kicks it in frustration, report her to the guidance counselor, and attend class.
This is the only day where Osana will accept salty snacks from Ayano, after the yellow vending machine in the cafeteria has been sabotaged.
Frame for Cheating (Friday)
On Friday, the player must wait until 8:15 AM, find a radio, use the radio to lure the gym teacher out of the faculty room, steal an answer sheet while she's distracted, and bring the answer sheet to Info-chan's room. After Info-chan makes a copy of the answer sheet, the player must pick up both copies, put the original back in the faculty room without getting caught, place the copied answer sheet in Osana's desk during lunch, report her to the guidance counselor, and attend class.
Blaming the Delinquents
Ayano can blame the Delinquents if she gets sent to the guidance counselor for any reason but to get them expelled, she must blame them for a different reason why she got sent to her office. Reporting the delinquents with the same reason twice, while they all absence or dead will result Ayano getting punished.
The lower the meter, the closer the rival is to being expelled. Each report will drop the bar by 20%. When the bar reaches zero, your rival will be expelled from Akademi.
In 1980s Mode, the expulsion process is slightly different.

All these items can be obtained by visiting the convenience store, but Ryoba will need a Fake ID to purchase alcohol and cigarettes, which can be obtained from The Yakuza. Each time, Ryoba must report her rival to the guidance counselor for having this contraband in school.
Frame for Cheating
On Friday, Ryoba must steal an answer sheet from the faculty room, place it into her rival's bag at lunchtime, and report her to the guidance counselor for cheating (unlike the main story, Ryoba does not need to duplicate the answer sheet).
