Lui Shirosagi

is a character appearing in the anime/manga series, Beyblade Burst. He is the #1 blader in the burst series as he has won 5 national championships in a row after defeating Shu and Valt. He is also one of the Supreme Four and is a member of team Ride Out.

Appearance
Lui has baby blue flaming hair and violet eyes. He wears a puffy white scarf, a teal shirt, and black and blue striped pants and white boots.

Personality
Lui is aggressive and quite rude. He has a personality similar to Ryuga and Sakyo. He owns a reverse-rotating dragon bey - Lost Luinor, who is similar to Ryuga's L-Drago and Sakyo's Ronin Dragoon. He also may be a sadist as he is seen to inflict harm onto Shu multiple times by creating the scar on his face and damaging his recovering shoulder.

As shown several times throughout the series, Lui only battles opponents that he deems worthy and is not afraid to voice his opinions on others, especially if they fail to live up to his standards. However, it is hinted that he is able to tell whether or not a blader is in sync with their bey, such as when he commended Gabe for having connected with his Gaianon and this could be the reason why Lui called Valt a terrible blader; he was able to see before Valt could that Valtryek had not yet at the time unlocked its true strength.

Plot
Lui is a member of Team Rideout, led by Gabe Brunai and is one of the Supreme Four. According to Gabe's memories, Lui was a transfer student and attended the same class as Gabe. Despite usually keeping to himself, he often went to observe Gabe while he was beyblade training and developed an interest on him and later joining the bey club.

He is first introduced at Zac's party as a "special guest". Upon his arrival he watches Zac and Valt's battle. After Valt loses the fight, he calls him a terrible blader. He respects skilled and talented bladers. But he is quite rude as he injured Shu on his eyes in the championship battle by knocking out his bey on Shu's eyes. He has won the 4th championship very easily by defeating Shu without any loss.
