Kebiishi stats are listed here

You'll only break swords if they enter battle in severe damage. Keep an eye on their hp and return when necessary. You should be fine. Kebiishi aren't too strong at earlier levels so tantous should be fine. Try world 2 and world 3 until they reach lv 40+. You can train them in world 6 after those maps.
