Yes, they've been here for a while...! Um... I've been here just over a year now and they all arrived... a few months after I did... I think? Out of all of them though, I think it's Rise-chan who's been here the longest.

[ Even as long as she's been here herself, it's still incredibly strange to think about in terms of months and years. It almost makes her wonder how much longer they'll all be here. ]

I'm not sure exactly how long though, I'm sorry. But it's definitely been a while.
