The Seven Emotions Tracking Spell

All living creatures have seven emotions and six desires. This was an absolute fact passed on since ancient times. 

The Tsukumogami, known as Little Cart, was a Tsukumogami enshrined by the Natsume family. However, it was imprecise to say that it was worshipped, as Little Cart can be considered as adhered to the Natsume family, and have equal status with the other members of the Natsume family. 

Little Cart was passed down by Mitsue Natsume's grandfather to Tsuyoshi Natsume, Mitsue's father before it was again passed down into Mitsue's possession. Counting from the time that passed after Little Cart became a Tsukumogami, it had been almost 50 to 60 years.
