You'd be surprised at what roaches are capable of, Madoka-chan.

[Reigen would cite several occasions where a cockroach almost killed him, but honestly, most of those just sound like his own fault when he says them out loud.]

But...well, it's not like I don't think about how I could get hurt or anything. I just tell myself I can handle it if it does freak me out, and once you say it enough times, it becomes true!
