Shu Kurenai (紅シュウ, Kurenai Shuu) is the deuteragonist of the anime and manga series, Beyblade Burst. He currently battles with his Beyblade, Storm Spriggan S2 Knuckle Unite. Shu Kurenai is also one of the Four Spin Emperors
Shu is quite tall for his age and has white hair and red eyes. His attire includes a pink shirt with a black tie, a black coat over his shirt, long black pants, and black shoes. His right hand sports a red glove. He has a scar over his right eye that was cut by Lui in a previous battle but which is usually covered by his hair.
Described as a genius blader, Shu is a favorite in his hometown. However, he does not rely on talent alone and is very hardworking when it comes to Beyblade. He is one of the best bladers to ever play the sport, managing to surpass Valt Aoi and win his first WBBA tournament in less than a year.
Shu is calm and patient, and prefers to be alone most of the time. He maintains a cool exterior in front of others, however underneath this lies a burning hot fighting spirit. He is quite standoffish towards people he doesn't know well, with Valt and Xander Shakadera being exceptions. Because of this, he is sometimes seen as aloof and even as a 'spoiled brat', as described by Rantaro Kiyama in anime episode 1.
In the anime, Shu is shown to be a good cook: this is because his parents are often busy and away from home so he has to do it himself.
☀ where he is first seen on a TV broadcast on Beyblade. He is introduced as one of the strongest Bladers around, and easily defeats his opponent with a single hit. During his journey home, he sees Valt training and questions what he is doing, to which he smiles and encourages him to continue. During Valt's first round match in the local tournament, he is shocked when Valt performs a Rush Shoot.

Valt is Shu's best friend, whom the former idolizes, and the two have known each other since kindergarten. Valt is continually inspired by the hard-work and focus Shu puts into blading, and continually seeks advice from him. Shu tends to drop his cold front in front of Valt and smiles more easily around him. He's also very protective of Valt and constantly looks looks out for him. Shu's faith in Valt is unshakable, and while others may become exasperated with Valt's empty-headed antics, Shu never stops believing in him. He views Valt as a worthy opponent and rival.

Because they are Valt's younger siblings, Shu also cares about them. In the Japanese version, both siblings refer to Shu as "Shu-kun" despite being younger than him, indicating that they're quite comfortable with each other.
Shu and Daigo originally only spoke in passing. Shu was the only one to notice that Daigo cheated during his match with Yugo, and saw how the guilt affected him. He approached Daigo privately and offered some words of comfort, even going out of his way to lie to Daigo's little brother, Souta, so that Souta wouldn't see his brother in a bad light. This spurred a budding friendship between the two. Shu and Daigo seem to get along, most likely because they're both quiet people.
