Commercially known as "Shade Gel", it blocks the effects of the sun from fatally harming vampires, however the effects only last 15 minutes after application.

After Tokyo Mayor Nishimura Ryutaro declares the termination lease on the bund and vampires as being dead, humans begin to mistakingly believe that the gel completely protects vampires from the sun for an indefinite amount of time. This leads to many innocent humans being killed or almost beaten to death. This period of time greatly resembles the salem witch trials.
