I don't think you made a mistake. You likely need the same heaping amount of EXP to level up from 62 to 99 with kiwame from 18 to 30-ish. Personally, I think leveling up a kiwame sword is more fun than a normal tantou, considering the extra perks like 2-slot troops, high stats and ability to dodge in daytime battles. And you most likely can take him to map 7-1 for grinding (though this hasn't been tested yet since my kiwame sword hasn't returned ^^;)
