His Gate target is Shozo Matsuki, who is in trying to keep his wagashi shop from closing.
Valkyrie first attacks Matsuki's apprentice Tetsuya Inagaki to thwart his delivery, with Shunpei thinking his friend was the target, then uses his human identity to trick Matsuki into wasting a majority of his wagashi.
When Kamen Rider Wizard interferes, Valkyrie takes Shunpei hostage to cover his escape. But Valkyrie eventually learns that Matsuki's hope is within Tetsuya and sees killing the youth to be the only way to fulfill his quota.
However, during the attempt on Testuya's life, Valkyrie is destroyed by Kamen Rider Wizard's Hurricane Dragon form with the Dragon Sonic.
