An Emblem Charge is achieved when both of the Emblems on any Emblem Charge System B-Daman are pressed in. This will power up a shot, due to the force acting on it.
When an Emblem Charge is charging up, the B-Der's eyes will light up with the Emblem's symbol representing the B-Daman they are firing from.
Kamon Day's Drive Garuburn was the first to use this, using it in Crank up the heat! Drive Garuburn! Upon doing so, the B-Dama shot out as a fiery blaze, showing off the power. It was able to take down all the pins in a single shot due to the combined power of that and the Drive core.
In same episode too, Misuru Hachuka appears and his b-daman, Slot Stinger performed it's first Emblem Charge. The shot performed in a zig-zag pattern and was used to navigate between a gap in two fences during a Road Fight challenge.
