so it's like a cult?

[That would explain a lot, though the stereotypical cult doesn't normally use apps to get their way, does it? They've certainly moved in on social media, but as Haruka has never joined a cult he doesn't know the ins and outs of their technological progress... Either way it's a bit unsettling to think about.]

and you keep talking about angels. is there anyone here named after an angel?

[All he knows about those is that they tend to end in '-iel' and he hasn't seen so much of that.]
