Alright, finished IDA Part 1. Man, the boss was a pain to take down. Admittedly, I've been running pretty much the same team since game start (Aldo, Miyu, Ciel, Bivette), so... certainly I'm not optimally prepared for everything that's not weak to Fire or Slash, haha. And it showed with fighting the boss. Although it has made me start to play creatively, moving my units into the Reserve to let them recover and what-not. Its AoE attack was a pain until I realized Ciel had a Type Resistance AoE buff himself.
After this I think I'll continue with the 1000 Year Ark Episode next. I only unlocked fishing, but now I'll go through more of it. Or maybe actually advance through the main storyline. I've done just about paltry progress there since Ch13.
Well, not quite. Did Ch14 as I did IDA Part 1. Hmm, well, I'll decide on what to do first some other time.
