Raidou's actually been kind of agonizing over this. He was going to get you a copy of Basho's Narrow Road to the Deep North, but he wasn't sure how ZEX would react to the underlying theme. However, he discovered Ono no Komachi while studying in the library, and so ZEX is getting this along with a book of Japanese myths and legends.

If he can find one, he'll also give you a small Inari statue with an explanation of their importance to the people in general and the Kuzunohas in particular.
