Picture	Real Name	Description
	Ikuto Tohoin	Ikuto is the main character of the story and is currently stranded on Airan Island. At extreme odds with his father, he ran away from home on a cruise liner, resulting in his arrival on the island due to a storm. Exceedingly kind and helpful, Ikuto's physical ability pales in comparison to that of the women on the island.
	Suzu	Suzu is the main heroine of the story. She is an honest girl and can be very spontaneous when excited. She is the first person that Ikuto meets on the island and possibly the closest one to him.
	Ayane	Ayane is Suzu's rival, always being defeated by her and wanting to win at least once. Despite her appearance, she is actually 16 years old, and being underdeveloped she is also jealous of Suzu's sudden growth.
	Machi	Ayane's elder sister. Despite her innocent looks, Machi is something of a sadist: she often tortures people with her voodoo doll, finding beauty in their pained, frightened expressions. She also tends to take the most dangerous methods to getting things done.
	Rin	An apprentice carpenter who is popular on Airan due to her somewhat tomboyish outfit and attitude, she was the subject of a lot of attention and romantic interest from other women before Ikuto's arrival.
	Chikage	Obsessed with scientific research, Chikage 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.
	Yukino	Yukino is the youngest girl on the island and has an affinity for animals. She is always seen riding an animal, most prominently a giant bear named Kuma Kuma, and is sensitive about her age.
