The president of the Student Council at Kyo's school, but also revealed to be the commander of the Oceanus, the base of operations for Kyo, Shizuno, and other Celebrants, and the leader of Celebram. Like Shizuno, there is more to him than meets the eye and he is only one who knows the true conditions of the present world. He and Shizuno had no prior history in the Maihama server before transferring to the Oceanus. It is later revealed that Shima's apparition (thus the reason why his Celebrant icon reads "CP-041" instead of his name) is actually a clone of his true self, a revolting Gards-orm who seeks to aid humanity's resurrection but remains with the Gards-orm. As a result, the data of his apparition has a different lifespan and is suffering dry damage. Shima means "Island" in Japanese.
