Mizuho Inada

Girl #1 Mizuho Inada spends most of her time living in a fantasy world, thinking of herself as a beautiful warrior. On the island, her mind breaks down and she begins to actually believe in the fantasy. In the novel, while believing she is an enlightened warrior, she creeps behind Kazuo in an attempt to stab him; he shoots her in the head. In the manga, she attacks Shuuya, but he escapes. She creates an overly elaborate shrine to her fictitious god, and Kiriyama kills her while she is worshiping there. (Source: Wikipedia)
