I got a bad feeling when you gave me those items, too, so I had them checked at a second-hand store I know.
It's not that rare to see items filled with scorn for an individual, but...
I've been in this business for a long time, but I've never seen anything with such strong hatred.
...The mallet was taken good care of for many long yearsuntil that incident you guys caused turned it into a tsukumogami.
*sniff*
*sniff...*
The tsukumogami mallet wanted to fulfill its original purpose...So I guess it manipulated you to make Seija suffer.
