Ok here is some translation, keep in mind that it can be not 100% perfect
2A – 1 hit instead of 2
5С – less recovery
6D – gives less drill gauge on whiff
Hariken – stance now has projectile-guard frames. Spiral gain is faster
632146C – higher damage, after hit amane left closer to the opponent (I wonder if you can combo after it?)
Summary It looks like they want Amane to use hariken stance to get drill gauge.
