The last koban reward is on F90 only, if you have a full team of Kiwame Tantou, they can survive until F90 as long as you equip them with full long range troops. Don't go after F90 because the rewards are only resources and you might end up spending more resources to repair. You shouldn't try to repeat a floor for koban nodes only since they gave only very little. General tips to gain more koban you should send expedition teams with sakura fubuki so they will reward you extra Koban /Tokens on great success.
