Girl #1 Mizuho Inada spends most of her time immersed in a fantasy world, imagining herself as a valiant warrior. On the island, her mental state deteriorates, and she starts to genuinely believe in her fantasies.
In the novel, convinced she is an enlightened warrior, she stealthily approaches Kazuo with the intent to stab him, but he shoots her in the head.
In the manga, she attacks Shuuya, who manages to escape. She constructs an elaborate shrine dedicated to her imaginary deity, and Kiriyama kills her while she is in the midst of worshiping there.
