Okano Kousuke's short, but gently narrated, video about visiting the Ghost Hunt pop up store last July 3 (I didn't know there was one!) popped up randomly for me and it was the best surprise. I didn't even know he had a channel!

I love how he remains a huge Ghost Hunt fan even after all these years. To me, the radio drama CD cast > anime cast, so he'll always be Naru.
