The B-Masters are among the elite of Crestland's B-Shots, each one holding dominion over the B-Shots in their designated area in the region. They answer to the only B-Shot that outranks them; the Grand B-Master. Kamon Day was once the B-Master of the Southern Area, but was 'exiled' from that position when he lost his Drive Garuburn's B-Animal and his memories after a harsh, devastating defeat by his older brother, Roma Day, the Grand B-Master of Crestland.
In War! The B-Master Battle, it is revealed that nobody holds the title of "Eastern B-Master". Roma offers the chance to become the Eastern B-Master to anyone who can win the B-Master Battle Tournament.
In Final Battle! Garuburn VS Dracyan, Riki defeats Dark Kamon in a Road Fight. Due to Kamon's memories being returned, he is reinstated as the Southern B-Master, while Riki is promoted to Eastern B-Master. This also corresponds with the statues in both sections of Crestland.
Unlike in the anime, Mitsuru Hachisuka is initially the South Area B-Master and Kakeru Ryugasaki is already the East Area B-Master. Like in the anime, Byakuga Shiranui and Genta Ankokuji are the West and North Area B-Masters respectively. Kamon defeated all four of them and is named All-in-One B-Master.
It should be noted that the concept of the Grand B-Master varies in the manga. The Grand B-Master is simply a title for the man who created the Road Fight and may not be passed on to the one who defeats him in battle.
It is unknown as to whether Ryoma personally passed on the title of Grand B-Master to Kamon. Kamon, however, became the A-Block Champion of the Phoenix Grand Prix after defeating Ryoma and was still called All-in-one B-Master.
