Uchide-no-Kozuchi

Known by a name that loosely renders as tap appear mallet, this enchanted hammer steps straight out of Japanese legend. Issun-boshi was its earliest bearer before the deity Daikokuten took custody of it. Within the narrative it surfaces as the proposed remedy for the shrinking curse afflicting Momo Ayase.

The mallet's renown rests on its power to shrink or enlarge a person and to fulfill wishes when handled correctly, the very trick Issun-boshi once used to stretch his tiny frame to a full height. Its look is heavily ornamented: a round head wrapped in detailed patterns of flowers and leaves, a shaft bearing a rippling wave motif, and a hanging tassel at its base all lend the tool a ceremonial richness.

In the folktale, the Inch-High Samurai Issun-boshi received the hammer from a demon that let it fall, then wielded it to make himself bigger, and afterward the relic ended up with Daikokuten. Within the manga, Kashimoto tells Seiko to head for Izumo Taisha and obtain the mallet from Daikokuten so she can undo what befell her shrunken granddaughter. Later, with Momo gone entirely because of the curse, a Head Masked Priest tied to an unidentified religious group took her to a shrine and used the legendary mallet there to bring her body back to its proper size.
