" As long as  at least one  sword in the party is above lv10, encountering Kebiishi will trigger battle with it. On the other hand, a team with all swords below level 10 can still trigger the appearance of the Kebiishi, but will not engage in any battle with the Kebiishi."

It would be fine but you wouldn't fight the KBC as long as none of your swords is level 10 or above.
