Shiori is a minor character in the Grand Blue series. She is a third-year middle school student and the younger sister of Iori Kitahara. Shiori shares her brother's blue hair and can be seen wearing kimonos almost all the time, as per her parents' wishes. While appearing very sweet and courteous, Shiori masks a more cunning and manipulative side. With no desire to take over the family inn, she pretends to have a brother complex in order to force Iori to take over the inn so she doesn't have to. She is highly skilled with technology, shown through the rabbit nanny cam she gave to Iori to keep an eye on him. However, she does show some traits that she is actually a bro-con.

Grand Blue
Among the seaside town of Izu's ocean waves and rays of shining sun, Iori Kitahara is just beginning his freshman year at Izu University. As he moves into his uncle's scuba diving shop, Grand Blue, he eagerly anticipates his dream college life, filled with beautiful girls and good friends. But things don't exactly go according to plan. Upon entering the shop, he encounters a group of rowdy, naked upperclassmen, who immediately coerce him into participating in their alcoholic activities. Though unwilling at first, Iori quickly gives in and becomes the heart and soul of the party. Unfortunately, this earns him the scorn of his cousin, Chisa Kotegawa, who walks in at precisely the wrong time. Undeterred, Iori still vows to realize his ideal college life, but will things go according to plan this time, or will his situation take yet another dive? [Written by MAL Rewrite]
