Drop rates of Kotetsu seem to be the same throughout each level. However, you'll have better chances receiving drops if you clear the battle with a better grade. So it's recommended to use a team that can consistently clear kebiishi. I find maps with more nodes to be better places to grind so that your swords have more opportunities to earn mvp and sustain Sakura Fubuki status.
