Chikage

Chikage is obsessed with scientific research, and wants Ikuto for the sole purpose of examining a real male and learning about the world beyond the island from him. She collects things that drift in from the modern world and plans on adding Ikuto to her collection, seeing him as a potentially invaluable source of information.

Chikage lives in the only English-style house on Airan with her elephant maid, Panako. She has a habit of reading mature magazines and gets misguided ideas from them to use against Ikuto. Although Ikuto believes her to be a calm, well-behaved girl, Yukino has noted that Chikage tends to perform strange experiments and questionable researches.
