Nisemonogatari

Koyomi Araragi has survived a vampire and several supernatural oddities, but this time the danger reaches his own family. His sister Karen clashes with the con man Deishuu Kaiki while trying to protect teenagers from fake charms and curses he sells, and her intervention leaves consequences Koyomi cannot ignore.

At the same time, a strange truth surrounding his other sister, Tsukihi, begins to surface, while two specialists in supernatural beings enter their lives. Between false heroes, false curses, and people who may not be what they believe themselves to be, the idea of a fake becomes increasingly complicated. Araragi is forced to consider that value does not always come from authenticity, and that something artificial can sometimes carry feelings more genuine than the original.
