>Rentarou catches on while investigating the library and nuters the sixth monokid who was supposed to act as a camera for everything. He plans with Kaede in order to take the mastermind down

>In order to make it seem believable Kaede wipes her memories while Rentarou/Kaede activates the trap nearly killing Rentarou but survives due to his talent

>Miu is killed due to a "bug" from gontas avatar. He gets the pyro execution

>Everyone wrongly believes ouma to be the mastermind and he goes insane over it. Kaito confronts him in order to stop him but realizes it just before he activates his trap that ouma was telling the truth. This brief moment of someone trusting ouma lets him die happily. In shame kaito flees the scene making it appear both died

>Later re appears and admits to his crime despite maki begging him to stop and proceeds to his execution

>The world is fucked up and the gang were sent to a station in space in order to escape it

>Rentarou is the SHSL survivor and the title is a reference to it with v3 meaning this is his 3rd victory.
