Yeah I recommend the Brave Set or Offense Set.

From 21 to 23, just play aggresively and you'll be fine.

As for 24, which is Kikuri and Sefia. Take note of the following.

1. Kikuri can negate Leader Skills, including Noel's Boosts.She's vulnerable to Paralysis.

2. Sefia can cleanse all your buffs. She's vulnerable to Curse.

3. It's best to defeat them both at the same time to avoid a massive AOE later on.

As for 25, which is Defense System, just play aggresively. If you do enough damage it'll Overheat, which hurts itself and skip its turn.
