This quest is not limited to just one completion, but multiple completions. This quest is obtained by running near the grassy area before the Daiku Cave in Kikaigahara. When you reach the area with your partner summoned, your partner will ask you to defeat 5 Ittanmomen and will reward you for doing so. This quest does not require you to talk to anyone to either acquire or turn in the quest other than having your partner summoned while running near the area.
