Kubikiri Cycle - Aoiro Savant to Zaregoto Tsukai - S01

Iria Akagami, a brilliant but sickly girl, is confined by her family to a secluded mansion on Wet Crow's Feather Island, accompanied only by a few maids. To stave off boredom, she invites a group of fellow geniuses to stay with her: Tomo Kunagisa, a computer expert, and her quiet assistant; Maki Himena, a gifted fortune-teller; Kanami Ibuki, a celebrated artist; Akane Sonoyama, a scholarly researcher; and Yayoi Sashirono, a master chef. At first, their time together passes uneventfully-until one of the guests is brutally murdered in the night, with no clear suspect or motive. As fear and suspicion grow among the island’s inhabitants, Tomo’s assistant steps forward to unravel the mystery, determined to stop the killer before another life is taken.
