Shu Kurenai (紅シュウ, Kurenai Shū) is the deuteragonist of the anime and manga series, Beyblade Burst. As a member of the Supreme Four and the runner-up of previous year's National Tournament, Shu fought with his Storm Spryzen Knuckle Unite.

In Beyblade Burst Evolution, he joined the American team, the Raging Bulls, with his new Beyblade, Legend Spryzen 7 Merge to battle in the World Championships. After losing to Free De La Hoya, he secretly became Red Eye, becoming an antagonist. After losing to Lui once again and revealing his identity as Red Eye, Shu created his new Spryzen Requiem 0 Zeta. For a while, he became possessed by his Bey, but was eventually saved by his best friend, Valt Aoi. He was the runner-up of the International Blader's Cup and a new member of the Big Five.

Shu returned in Beyblade Burst Turbo as the new owner of the Raging Bulls with his new Turbo Beyblade, Turbo Spryzen 0Wall Zeta'. Since the Evolution finale, Shu became the mentor of Fubuki Sumiye and later tried to help free Aiger Akabane from his corruption and master his Turbo Achilles' Turbo Awakening.

In Beyblade Burst Surge, Shu returned as the mentor of Lain Valhalla. After Lain left him to make his Flare stronger, Shu made his new Lightning Beyblade, World Spryzen Unite' 2B, to help Valt defeat Lain in the Legend Festival finals. He later teamed up with Lain in the Ultimate Tag Series tournament and the two became the tournament's runner-up team.

In Beyblade Burst QuadDrive, Shu returned with his new Quad Beyblade, Astral Spryzen Over Quattro-0.

In Beyblade Burst QuadStrike, Shu helped assist the wbba. with some research on the ancient ruins and the elemental powers. With the introduction of the Aether Beystadium, Shu evolved Astral Spryzen into Bolt Spryzen Xanthus-Q Quattro-Q+Jaggy-1.

Shu is quite tall for his age, with shaggy white hair and bright crimson eyes. He also has a scar over his right eye, inflicted by Lui Shirosagi in a previous battle, but it is usually covered by his hair, and therefore unseen until he lifts his hair when he wins a battle.

In Burst, his attire consists of a short-sleeved pink dress shirt with a black and red striped tie, a black high-collared vest with a white interior, long black pants, and shining black shoes; his vest bears a red Beyblade symbol on the left side. On his right hand, he sports a red fingerless glove with yellow accents and a square cuff.

In Evolution, his Red Eye attire consisted of a dark grey-and-red streaked mask that only showed his eyes and mouth. He wore a long white sleeveless tailcoat with a high collar and red accents, a black and red bodysuit underneath, and a matching gauntlet on his left arm. Upon donning the mask, his voice became noticeably deeper than before, though it is unknown if the mask had a voice-altering feature, or if he was disguising his voice by speaking in a deeper range.
