Drowning

Drowning is one way to eliminate of your rival or chosen student without bloodshed.

You can drown students in the fountain located outside the school building, in one of the two bathrooms inside the school building's first floor, or in the massive tub in the Shower Room. As of June 16, only Kokona Haruka will break paths and go to the girl's bathroom or look at the fountain.

If you are unable to dispose of a body after drowning or if you just want to store a body for the time being, you can hide corpses in the bathroom stalls.

If a student is covered in blood or water, they will run to the Shower Room to change and take a bath. There you can sneak up behind them and drown them.

You can drown Kokona in the fountain on Monday at 7:05 AM, or drown her in the toilet on Thursday at 7:30 AM.

Kokona will stand near the fountain until the two last students in the row have nearly passed, which makes it nearly impossible for the students not to see her drown, but on the other hand, it's easy to get to the incinerator from the fountain. Being drowned in the toilet will not be seen by any student, but getting to the incinerator is a lot more difficult because of being seen whilst carrying the corpse.

A supposedly not intentional feature is that you can prevent the two last students from seeing Kokona drown in the fountain by starting a conversation with her and then waiting for the conversation timer to end, slowing her down. It has to be timed right, because if Kokona is too close to the fountain, she will avoid talking to you.
