As long as you haven't choose any battle formation when you close the game, it doesn't count.

I think maps with longer routes will have better chance at having kebiishi spawning, but there's no best or worst map to spawn Kebiishi imo. It depends on what sort levels/swords you're bringing to the map. The stage 2 event map has a level limit, so if your swords are in that range, then go for it.

Good luck!
