9S, for various reasons, is at times suicidal. I will always, always warn and ask before mentioning it in a thread or a post, but if you just never want to interact with suicidal ideation and nihilism at all ever, please let me know!
This also functions as a "can 9S read your text messages/emails/be a nosy shit in your technology" and a "do you mind possible vague Nier: Automata spoilers" post.
