Syo Kurusu (来栖 翔, Kurusu Shou) is a student of Saotome Academy, sorted into S Class. He is a member of ST☆RISH and the twin brother of Kaoru Kurusu. He is voiced by Hiro Shimono (下野 紘, Shimono Hiro).
Syo is a short boy with blond hair that is parted to the right, shaded with pink, and he keeps the bangs out of his eyes with red bobby pins. His eyes are blue, but in the anime, his irises are black. His ears are pierced, and he paints his nails with black nail polish.
He is probably the most uniquely dressed character in the series. This is because he usually wears much different clothing than the normal uniform. He wears a hat most of the time to make himself look taller.
He is described as a "stylish" person, and is also recognized as being very "cute". However he hates it when people call him that.
Syo has a lot of energy and has an upbeat personality. At times, he can be very hot-headed and a bit defensive, especially when it comes to him being teased about his height. When Syo was a child, he was hospitalized often due to his heart condition and cursed the body he was given. He was told that he would only live to the age of 12. Even though Syo was told this, he stayed lively, and even beat his odds by living longer than his life expectancy and is still living strong. Due to his heart problem, Syo had a great desire to make himself and his body stronger, so he eventually took up karate and is on-par with his idol, Ryuya Hyuga.
In the game, he actually suffers from a heart condition, to the point that he will collapse if he overexerts himself or if he gets too excited. Because of this condition, his physique is rather weak. After seeing Ryuya Hyuga on TV, he is motivated to become an idol despite his heart condition and highly idolizes the man, who has become his teacher in the S Class. Also, it is revealed that Syo has a younger twin brother, Kaoru. His twin can be very overprotective of him, swearing that he will always be the one to protect and look after him despite being the younger twin. In the game, he stated that their mother is an orchestra conductor who works mostly overseas and their father is a stylist in Shining Agency.
In the anime, Syo is a childhood friend of Natsuki Shinomiya, who caused his phobia of heights by chasing him with a net to the top of a tower, nearly causing him to fall to his death had he not grabbed him. Syo often competed in violin competitions against Natsuki.
In the game, he and Natsuki did not know each other in the past, unlike in the anime.
Kaoru, his younger twin, is taller than him. Coincidentally, Syo and Kaoru's voice actors are best friends in real life.
Syo and Natsuki's birthdays are on the same day, June 9.
The Kurusu twins share the same birthday as the Hitachiin twins from Ouran Highschool Host Club.
In the anime, he is the one with the acrophobia while in the game it is Ittoki Otoya.
As a running gag, he is usually forced to crossdress both in the anime and game.
Syo has been rated the best Otome character in B's Log.
Syo's star sign is the Gemini, the sign of the twins, coincidentally, he himself is a twin, with the other being Kurusu Kaoru.
As of the first episode of the second season, Syo is the only character to have his exact height stated in the anime, as stated by Ai, Syo is about 161 cm tall (which is 5 feet 3 inches; Ai also suspects that Syo is actually no more than 160 cm tall or less according to Ai's visual judgement.).
The average height of males in Japan is 170–172 cm (roughly 5 feet 7 inches to 5 feet 8 inches) Syo is 9-11 centimeters or 4-5 inches under average height.
He and Natsuki have the greatest difference in terms of height, being 25 cm or nearly an entire foot shorter than Natsuki.
Syo is seen to be very acrobatic, along with Ittoki Otoya
Along with being the shortest member of ST☆RISH, Syo is also the youngest member of the original group (Cecil is the youngest of the entire group as he is Otoya's younger half-brother through their mother).
Due to his heart condition, Syo had been told he would only live until he's 12.
According to Cecil in episode 2 of the second season, though Syo is small, he's very athletic and his cute looks yet masculine personality is his appeal, but his violent temper causes conflict with others.
As of the second season, it's been confirmed that Syo has gotten over his fear of heights, as he jumped into a tree chasing after Cecil in episode 2 and willingly jumped a great distance numerous times during a filming session that was incredibly high up and once without a safety cable in episode 3.
In the All Star Symphony Pack, Syo is stated to be from the Aichi prefecture. He is actually from Nagoya.
He had good results on Athlete Paradise Sagusa.
Athlete Paradise Sagusa is a sports-based variety show.
Recording stresses him out, but it is easier with trusted friends [Ai and Natsuki].
He has memorized all the lines to the movie, Space Superman Majindaa.
He hates wasabi.
His favorite food is dairy products.
In the 2015 "Ideal Husband" category of the "Top 20 Characters Otaku Want to Marry," Syo placed third overall, placing the highest of all the Uta no Prince-Sama characters that were on the list.
His overall appearance bears a striking resemblance to Finny (Finnian) from Kuroshitsuji.
