This is Demon Kokugure, a performer and artist, and serious sumo fan. Here he is doing commentary for NHK’s sumo broadcast (he’s doing a full 5 hours for them, very unusual). Don’t judge this book by the cover, this guy knows his sumo, frontwards and back. I’m looking forward to being able to hear his insight when I watch the DVD recording tonight.
(I’ll upload a better image tonight as well.)
