The head maid and Iria Akagami's trusted assistant: Rei Handa. Not much is known about her, though it's assumed she's been with Iria for the longest and shares a strong bond with her. Besides that, like the Chiga triplets, Rei has chosen to stay with Iria no matter what.

Rei herself is a calm individual with the polite attitude of a maid. Ii initially believes she may be cold, though that quickly dissipates after having a friendly conversation with her. ~!While Ii is on his way back to the mainland with Tomo Kunagisa, it's revealed that the Rei attending with him is actually Iria. Iria and Ii reveal that the "Iria" that was around on Wet Crow's Feather Island is actually Rei and that they switched for fun and to see if anyone would notice. Ii guessed this as the actual Rei threw Hikari Chiga under the bus, which wouldn't make sense for Iria to do, along with a few other details.!~

A dropout from an elite Houston-based program for teens is on a visit to a private island. Its mistress, virtually marooned there, surrounds herself with geniuses, especially of the young and female kind—one of whom ends up headless one fine morning.

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.
