Sakurano is student council president and is the main representative for the school. In the manga, he is best friends with Subaru Imai. Furthermore, when they are in the High School division, he and Subaru posed as ghosts looking for a victim. It is revealed in the manga that he has three Alices, teleportation, intuition, and wish/prayer (telepathy).
Sakurano knew Subaru since elementary school, so they are very close. It is revealed that he knew Mikan's parents when he was young. Because of this, he and Subaru care for Mikan very much and will protect her no matter what happens. He has once made an Alice Stone for Mikan, and had it follow her wherever she goes. His Alice Stone was the one who helped Mikan get to Natsume during the Alice Stone game. He is rather fond of Mikan.
He helps Mikan in a lot of situation. In a special chapter about Subaru and himself, it was shown that they used to call each other names and were caught by Jinno for detention. When he was young, he is shown to be very arrogant only to Subaru while he pretended to be nice to others.
