There's not really any sure way to level up faster. You just need to grind a lot. You don't say what type of swords you have at 81, but if they are anything other than tantou, you should get to map 5-4 as that will be the best experience gain for that level.

Events are usually a good way to level up pretty fast, though I wouldn't recomend the current Underground Treasure Chest as it doesn't give much better exp than normal maps at that level.
