He had a long goatee and moustache. The top of his helmet was shaped like a shrimp's tail.
Eibi had a humorous personality as he joked with the men before battle.
It is assumed that he worked his way up the ranks to reach the position of General.
Ei Bi is first seen rallying the second wave consisting of 8,000 troops and warns the Hi Shin Unit to be alert as the new units are being targeted by the enemy. He spurs them all with his words before ordering the charge at the Wei troops. During the battle, he is told that 1000-man commander Jou Han is having trouble and orders reinforcements be sent to them. He notices that the Hi Shin Unit have become a rallying point on the field.
On the sixth day of battle, Ei Bi assigns the Gyoku Hou, Hi Shin and Gaku Ka units to the reserves in the rear. He states that being there will work to their advantage as if Rinko gets past the lines, they can catch him by being in the rear. Ei Bi commends Shin and his unit on breaking into Rin Ko's camp, stating that both he and Do Mon recognize their strength before mentioning that they might be in for some rough weather from the looks of the clouds. When the battle begins, he notices enemy movement and what appears to be the cavalry running around in circles. Ei Bi orders the defense on the left and right flanks to be reinforced but this works to Rin Ko's advantage as the Wei army breaks into the center of the Qin army, targeting Ei Bi.
