Kōichi Yamadera  (山寺 宏一 Yamadera Kōichi) is a Japanese actor, voice actor, and narrator affiliated with Across Entertainment.

He is known for his roles as Spike Spiegel from Cowboy Bebop, Beerus from Dragon Ball Z and Dragon Ball Super, Togusa from Ghost in the Shell, and Ryoji Kaji from Neon Genesis Evangelion.

He is the Japanese voice of all five members of the Monokuma Kubs in Danganronpa V3: Killing Harmony.

According to Danganronpa V3 official blog, Yamadera is the first person it comes to mind when you think of “the same person voicing multiple characters at the same time”. No one has as much “multiple characters” experience as him and no one has that same high quality in making themselves sound like completely different people. He took the individual quirks of each Monokuma Kubs and made all of them unique.[1]
