Honestly this sucks, if Sakurako died.
Tooru legit came into her life and ruined it. Killed her mom and injured the other psychopath's sister, then she ended up abandoned and then involved in a yakuza people disposal facility doubling as an orphanage, and then as they're all getting mass murdered because that psycho's getting revenge, Tooru finally kills her too.
Sakurako's life just sucks and it's all because of him.
Wtf is up with the blond guy's logic too? Calls them mass murderers as he's mass murdering them?? Bruh y'all are hired by the same guy asking you to do all this shit. None of y'all are doing this for fun
