Hello bedbros Does anyone know the name of this Bedman player? He is supposed to be the 9th best player at the Japanese arcades, but I don't know japanese so I don't know how is he named. Also, what are the best bedman players at the moment? I only know Mun, Tsubu and Mitsuru, but it seems Mitsuru hasn't played GG for a long time.
