The top B-Shot in the West Block with his B-Daman is the rapid-fire type Lightning Dravise.
Contrary to Riki, he is cool and reserved. He is proud and has a sharp mind. He is a boy of many mysteries who makes no attempt to open up to any of the other B-Shots.
He senses some sort of power in Riki that is different from the other B-Shots. Though he does not think much of Riki at first, he eventually starts to consider him a rival.
Samuru debuted in B-Daman Crossfire near Riki's working booth at the town market. He was being spoken to by his Lightning=Dravise unknown to Riki, Riki confronts him about the voice but Samuru simply walks away without a word. Later on he is seen by Riki within a B-Daman Facility training with his Lightning=Dravise. While practicing he fires off a combination of shots that from themselves into a Dragon and strike the wall showing off Samuru's power. After he is finished he and the other facility members welcome Riki. During testing Samuru receives a perfect score on stage 2 once again showing off his power. After testing is over Samuru stays behind to detail the real strength that Riki showed by leaving a crater on the doors.
Samuru returns in B-Daman Fireblast with his new B-Daman Sonic Dravise, in episode 01, at the end he is shown using his new Emblem Charge Shot, the "Speed of Sound Hurricane", to demonstrate his power. He then is challenged and stalked later by Misuru Hachuka, and end up battling him and his Slot Stinger, easily defeating him.
