On the Schemes menu, the description is: "This scheme will end with your rival being drowned."
How to Drown a Student
When able to drown a student, a button will appear on the HUD that says "Drown". When pressed, Ayano Aishi will grab the student by the head and hold them under the water until they stop struggling. After letting go, the corpse will fall to the ground. Any student within the observable area will scream in horror and then act upon their persona. If Ayano does not dispose of the corpse, the police will be called. They will note that the student was drowned, but will be unable to find the perpetrator if there are less than 5 witnesses and there are no other murders that point towards Ayano as the perpetrator.
In order to drown a student in the bathroom, Ayano must first obtain emetic poison. It can be bought from Info-chan for 10 panty shots. Next, they must wait until lunchtime and for the student to start eating their lunch. Ayano must then distract the target by laughing or with the radio, which causes them to put down their lunch and investigate. While they are distracted, she must put the emetic poison in their lunch. Being noticed by other students will cause Ayano's reputation to drop, and being noticed by the target will make them disgusted and refuse to eat their lunch, removing the chance to drown them. If Ayano successfully poisons the food unnoticed by the target, they will eat it and feel sick, causing them to go to the nearest bathroom to vomit in the toilet, where she can drown them.
Alternatively, students who clean toilet bowls at Cleaning Time can also be drowned while they are cleaning a toilet. However, this is much more risky as other students will also come to clean the toilets and may witness the corpse. This is especially difficult in the third floor girls' bathroom, as the bullies will go there and gossip during Cleaning Time. So Ayano must close the stall door to prevent other students from discovering the corpse.
Ayano can also drown students in the fountain in the plaza by writing them a note to meet them there. She will then have a twenty-minute period to drown her target. Unless lured there, no students will currently go to the fountain.
Ayano can also drown Kokona Haruka in the first floor girls' bathroom in the eastern wing of the school through the use a of scripted event, and in the future, the rivals may be drowned using this method as well. As of the June 16th, 2015 Build, Kokona will break paths and go to the first floor girls' bathroom on Wednesday at 7:30 AM. While she is there, Ayano can drown her. Kokona also used to observe the fountain from 7:05 AM to 7:07 AM on Monday before the November 15th, 2015 Build, which allowed the player to drown her immediately.
In the future, Ayano will be able to drown rivals in the swimming pool, or in the massive tub in the Shower Room. These methods are not fully implemented yet, as the game is currently incomplete. It is unknown when this will be implemented.
In the future, one of Osana Najimi's unique elimination methods will involve the pool. This unique elimination method will be classified as drowning. She will fall asleep sunbathing by the pool during lunch time on Wednesday, at which point Ayano will need to take the weight from the gymnasium and tie it around her hair. The latter will then shove the weight into the pool, drowning Osana under the water. Osana sunbathing and the way to eliminate her will be foreshadowed before it happens, and YandereDev may decide that the event will not happen unless certain conditions (such as stealing sunscreen and giving it to Osana) are met.
