Oji Tanaka was told his bandmate and musical prodigy Watanabe was killed by a deranged fan. He and the other members of their band, Black Heaven, spent an entire decade believing Watanabe had died as a rock and roll legend.
The truth was not quite what they thought.
On a trip to America Watanabe and one of his fingers fell victim to a lobster-related shenanigan. This offended a nearby local. Who this man is, his name, how he became so strong and what he has against tourists has never been revealed. However, Watanabe soon met his end after being tossed through a billboard by this man.
In the shows original language this mysterious man was played by an equally mysterious person by the name of Mike Pepe. When the rest of the show was dubbed into English Beau Billingslea, the lead actor, also played this character.
