[It's a topic that Atsushi is hesitant to dig too deeply into, for similar reasons: Knowing that he could up and disappear with no trace is disturbing to him. It's hard to relax when he considers that it could happen again.]

I haven't heard of it happening to anyone else... I don't know where I went, either. I woke up on the beach like everyone else, and they told me that they hadn't seen me for months. To me, it felt like I'd just seen them the day before. It was... 'weird.'

['Weird' being a word he chooses to prevent his own internal panic.]
