I can understand most of the shit Yuuko has been up to, but she didn't even try to explain why this was necessary. Is she literally saying
>Bro, I had to try to kill everyone here so they'd realize how epic the new OS is and shape up for the new mission
??? Like there aren't a million other ways of accomplishing that goal that don't involve doing this? And Takeru doesn't even press her on it at all.
