From Quiz "Battle Royale": Fight Right And With Gusto
Answer:
Nanahara
Yuko had been armed with a vial of poison powder, which she put into a dish of noodles intended for Nanahara, who was being nursed to health by the girls in the lighthouse. She wanted to kill him because she had seem him get into a struggle earlier with another boy, Oki. This involved a hatchet and lots of rolling around, and resulted in the former accidentally getting killed. She was convinced Nanahara had done it on purpose and wanted revenge. Unfortunately, as she was about to bring him the dish, Yuka came in, took it from her and ate it, thinking it was hers. Less than two minutes later she was dead. This set off a paranoia-induced shootout that left all the girls in the lighthouse dead, except Yuko, who promptly jumped off the lighthouse from sheer guilt anyway.
