Shinya Sakaki (逆木 深夜, Sakaki Shinya) is the attendant of Kanami Ibuki.
I judges Shinya to have a mild-mannered way of speaking and expression. He considers himself and I to be similar, due to their respective relationships with Kanami and Tomo Kunagisa. Though he speaks badly of her personality, Shinya holds an unconditional affect towards Kanami.
Shinya has a mild-mannered appearance and wears designer clothes. He is four inches taller than I.
After Kanami regained her sight, Shinya taught her how to paint, but in one month, she had surpassed him, after which he stopped painting himself. When Kanami was invited to Wet Crow's Feather Island, Shinya accompanied her. He is one of the two non-geniuses on the island, the other being I.
The Beheading CycleEdit
Shinya and I run into each other on the morning of I's third day on the island. Shinya convinces Kanami to paint I's portrait. At dinnertime, all twelve residents of the island gather together to eat. Hearing that a new guest will be coming to the island, Shinya asks for details. After dinner, he ends up in the living room with Maki Himena, being served by Hikari Chiga. When I and Tomo come in, Shinya asks how the modeling went, and apologizes to I for Kanami's personality. After an earthquake hits the island, Shinya calls Kanami to make sure she is alright. He reports that some paint has spilled, but that Kanami is unharmed.
