Vera didn't bother to reply to Mitsunari's question as Youji was already doing so, although she had also arched an eyebrow; there were those who didn't have this sort of technology before and they were able to figure it out after a while, it wasn't that hard.

At the message that Youji sent to her, she gave the kid a faint amused/possibly, slightly, maybe fond smile before showing the sent message to Mitsunari. She then typed out another message for the newcomer- "It's exactly like Youji said, just do what I'm doing but click the 'send' button instead of deleting the message. It isn't that difficult to use and you'll be able to get the hang of it after you fiddled with it first. That's how most of us figured out how to use them."
