Naruto Shippuden: Honoka

While researchers worked on the Ultimate Summoning Beast, Honoka was assigned to restrain the beast using her sealing techniques. However, at some point in time the beast got too powerful for her technique to restrain and it got loose. The researchers called for her to do something as the beast began to kill them. Eventually, she was the only one left, and when her sealing technique failed to restrain the beast, she called out for help, though there was no one to hear her while she was killed.
