Sorry for the late reply! Honestly, I'm a bit surprised you found Oodachi hard to level up @.@. For me the hardest one is tantou haha since they die so easily, I can't bring them to Era 5 (which gives a whole lot of EXP ;; A ;; ) unless they are over level 60.

As the person already answered you, the easiest way is to put the Oodachi (or any sword you want to level up for that matter) as the leader of a STRONG team in a map with many battle (since your swords get a -10 fatigue points every time they enter the map), REGARDLESS of the scouting stat :P. The strong team would guarantee that you win the battle even if you choose the wrong formation.

Personally, my choice of map is 4-4 and any maps in Era 5, but if you want to play safe and not damage your weak sword, go to Era 3 instead until the sword reach Toku. The team should contain 2 weak swords maximum. Leader is the weakest sword, since they get 1.5xEXP, they would level up quite fast. The rest of the team should be high leveled swords that can kill enemies in 1 hit, eg Iwatooshi lv>70 or Oodachi lv>40. Just turn back when you have to reach the boss node, or if you're not afraid of Kebiishi, just keep going on boss node (they give heaps of EXP afterall :P)

Leveling up any swords does require patience so just keep going :). It will be worth it when they reach Toku and when they are high level.
