The attendant that came with Kanami Ibuki to Wet Crow's Feather Island as her caretaker: Shinya Sakaki. A friendly man that assists Kanami when needed, though she can be stubborn. He cares for Kanami greatly, yet does speak ill of her personality towards others. He considers himself and Ii to be similar as they both aren't geniuses and are companions of actual geniuses, though the similarities end there. Originally, Shinya was the one that taught Kanami how to paint after her vision was restored. ~!As Akane and Kanami switched places, Shinya knew and was assisting Kanami, now acting as Akane, with her plans. In the end, he helped the real Kanami escape the locked room and didn't care if others died. Jun Aikawa states that Shinya has likely been with Kanami for a long time, and has been with her even before she claimed the original Kanami's identity.!~

It's the vacation of a lifetime, a trip to a remote island filled with geniuses–and murder. 
 
On Wet Crow's Feather Island, a tiny speck in the Sea of Japan, lives Akagami Iria, the exiled daughter of a powerful family. Born into great wealth, she was a princess of the highest pedigree–until she was cut off by the leader of the Akagami Foundation. For the last five years, she's lived on Feather Island with her maids. But she hasn't been alone. She has invited the best minds Japan has to offer to come and stay with her. 
 
And so nineteen-year-old college student Ii-chan and his best friend, computer genius Kunagisa Tomo, find themselves as Iria’s guests at her elaborate mansion. Surrounded by fascinating women – a chef, a fortune-teller, a scholar, and an artist, not to mention his own friend Tomo – Ii-chan is feeling a little overmatched intellectually. But the sudden discovery of a grisly murder sends the island into shock. And Ii-chan discovers that he does possess a bit of genius: the ability to discover what is real and what is fake, who is who they claim to be and who is a killer.
