Crisis + Big Change

My score increased a lot with Aria and Astra at 2 stars. Crisis hard Score increased by 9000 by switching Miyabi to Aria. Crisis Remiel setup: Score increased by +4000 (cap) by switching Yuzuki to Aria. Miyabi setup: Score increased by 5000 by switching Yuzuki to Astra. It's amazing that Astra, even without its signature weapon and at only 2 stars, increased my score by 5000, considering Yuzuki also didn't have her signature weapon.
