You're welcome. :)

For tantou/waki around level 15 I would go with the maps in world 2 as long as possible (the level limit for 2-4 is level 32). The reason for this is there are no enemy long range troops in world 2, so those little guys hardly take any damage and get S-rank battles non-stop. Again make sure to return to citadel before boss node, KBC aren't very nice.

Once they are nearing level 30, then I take them on to world 3. Once they hit mid 45-50, take them to world 6. They can survive world 6 earlier, but 6-1 has some really hard hitting yari and I don't like taking chances. Maps 6-3 and 6-4 are a lot more forgiving and better for grinding tantou/waki once you get there.
