Акаґамі Ірія

The heiress to the Akagami Foundation who is exiled on Wet Crow's Feather Island: Iria Akagami. A girl that is absolutely fascinated by geniuses, wishing to be around them for their impressive minds. As such, she invites geniuses from all around the world to live with her for periods of time. On top of letting others live on her estate, Iria also pays them a hefty amount to live there, should they accept. Upon learning about Jun Aikawa, she becomes utterly infatuated by her and believes she is a genius among geniuses.

Iria is emotionally immature and not too sophisticated as her position and wealth may suggest. At times, it's not rare to see Iria pull tricks for her fun. Besides that, she has not too much trouble being social and friendly, though she can give others the cold shoulder at times. When it comes to Rei Handa and the Chiga triplets, she considers them family and loves them very much. Iria is said to suffer from D.L.L.R. Syndrome, where she wishes to harm others. Teruko Chiga states that she killed her twin sister, Odette Akagami, which caused Iria to be exiled. This was later proven to be false, making the actual reason for her exile to be unknown.

When Ii and Kunagisa are going back to the mainland, it is revealed that Iria and Rei switched places. She states that the only reason she did it was for the sake of entertainment and that she wanted to see if anyone noticed, much like Ii did by chance.
