With her masochistic tied to the bed in a spread eagle position, Hinako lines up a series of Japanese sparklers above his body. However, these sparklers, known in Japan as Senko Hanabi are a form of traditional Japanese fireworks that are characterized by their unique tips that drop hot fireballs when ignited. However, fireballs are not guaranteed to drop every time, with duds being somewhat common, so it's hit or miss. So that means this masochist, all tied up and exposed, will just have to have to wait and see just which ones will drop fireballs.
