Yuki Mizusawa

Beyblade: Mercury Anubius 85XF Special Move: Brave Impact

Yuki isn't very strong nor experienced in beyblading, but he makes up for it in courage. His grandfather told him about the star fragments, making Yuki observe the stars as the 10 fragments hit earth. They split up and his bey was shining as well, which made him look for Gingka to inform him of the danger that the world would be in if the star fragment's power was taken by evil people. However, he doesn't know that Johannes, a servant of the evil group, was already following him and on his own hunt for the star fragments and the legendary bladers. He makes Yuki battle him right before he can meet Gingka and almost defeats him.

Kyoya sees that he's having a hard time battling, but decides to deny his plea for help. Fortunately, Gingka and his friends show up to save him and make him part of their group.

He's legendary blader of the Solar System (Mercury) and awakens in his battle against Ryuga.
