The oni seemed more on target with the crab then it did against him.  It would be a big mistake no less to ignore a scorpions sting.  He would scowl as he took off with Hida-san and went to corner the Oni out in the garden to engage it one on one.  He would grumble lightly as he might have to resort to pinpoint strikes like the eyes or the joints rather then just outright striking the creature.
